1) That's pretty much it. With 12v on, you can static time it to get it close enough to start. Crank the engine with the coil wire off to get oilpressure to register on the gauge. Put some gas in the float bowl too.

Yes, #1 cylinder is at the FRONT of the engine.

2) Yes, you can pull the tranny & T/C out the bottom all by themselves, sometimes easier & quicker if you pull the tranny hump and support the tranny from above. I've used a 4x4 piece of lumber laid between the dash and the tailgate and a bunch of ratchet straps. Others will stick a cherry picker in through the door to support the tranny. Mating the tranny up to the motor is always the funnest thing...

funny:lol: by myself, I found it to be more of a Shakespearean Comedy! get some refreshments and have a couple buddies come over and help manhandle the dang thang! It can be done by yourself(if you have masochistic tendencies)
 
Thanks for all the responses & tips. . . Been taking a break for a few days while I wait for the carb. and dizzy parts (which hopefully arrived today). Also picked up a few days of "real" work which has taken precedence!

you got coolant in the motor, oil in the motor, everything torqued down right, all belts tight, fuel to carb and timing static set, no tools laying about....I'd bump the motor a couple times and then crank it-course, if it starts on one of the bumps, let it go. check for fuel leaks first, oil leaks second and water leaks last. let it warm up and shut it down to adjust the valves. Might have to stop inbetween things to make adjustments to carb and dial in timing. Nope, you will have to stop inbetween to adjust carb and timing.

On the coolant - I drained and flushed the entire system, so I'm starting from completely empty. I filled through the radiator cap until full - is any of the coolant getting past the thermostat and into the head? I don't want to start/run the motor w/out coolant in the head as I assume that'd be bad? Whats a good way to bleed the system and is that necessary? (sorry for the stupid question - my other project car doesn't have water, just A LOT of oil!).

When you say "bump it a few times", do you mean w/the hand crank or just hit the starter w/a couple of quick bursts instead of letting it crank for a while?

1) That's pretty much it. With 12v on, you can static time it to get it close enough to start. Crank the engine with the coil wire off to get oilpressure to register on the gauge. Put some gas in the float bowl too.

Static timing - do I do this by just turning the engine over w/the starter? Maybe not hook up the coil so it won't start?

How do I fill the float bowl directly? (once agin sorry to be stupid about this! On my KTM 300, I'd just tip it on its side to fill the float bowl, but I'm pretty sure I won't be able to tip the 55 on it's side).



I borrowed a timing light, coolant system pressure tester and vacuum gauge this afternoon. . . hoping to put them to use this weekend. . . we'll see.
 
Satic timing. set the engine to TDC #1, dizzy rotor pointed in the general direction of where sparkplug wire #1 is in the dizzy cap. put the dizzy cap back on , all electricals hooked up & key on. Rotate dizzy body counterclockwise to just where you hear the spark jump to the rotor (or use a test light somehow, but I usually do it by ear). that's how I do it.

Those big brass vent tubes sticking up at an angle over your venturies lead to the float bowl. Pour gas in one of them.
 
Got the carb, spare dizzy for parts & pertronix in the mail yesterday, so I THINK I have everything I need. . . once I finish rebuilding the dizzy & bolting everything back on, I'm hoping to try to fire it up.

One quick question - where/what does the solenoid valve wire connect to? One of the two wires is grounded to one of the mounting screws. Where does the other go? Mine was chopped right off VERY close to the valve. I spliced it longer, but don't know where it goes. . .

Thanks,
Tom
 
The carb fuel cutoff solenoid? It gets a hot 12 volts when the key is on. Some get it from the emissions box, some get it behind the dash somewhere...
 
IT LIVES!!!!!!!!!

I will post more info later, but wanted to share that I just got the engine running at long last. Even though I rolled it outside before cranking it over, I've definitely breathed in my share of exhaust for the day.

A few quick questions:

The oil pressure, or lack thereof: When I ran the oil pump w/an electric drill, my wife was looking at the gauge and reported that the needle moved to just under 1/2. When cranking before running and during a brief run, I never saw the oil pressure needle move. . . at all. Worrying I know. I spent A LOT of time trying to make sure the distributor was seated in the oil pump slot. I did some rough depth measuring of seated vs non-seated distances and as far as I can tell, it should be seated. After seeing no oil pressure on the gauge, I pulled it back out and did the verifying all over again and as far as I can tell, it's in. Is there any other way to be absolutely certain? The clamp for the distributor is not up as high as it could go. It's maybe 1/8" below that point if that makes sense.

Once I get comfortable w/the oil pressure issue, I'll let it run and check the timing. After that. . . what's next in terms of smoothing it out?

I'm hoping to be able to drive it around the block this afternoon since it's supposed to be snowing (a lot) for the rest of the week. . . we'll see if I can get it done!

I'll post more details & photos later. I need to eat some lunch before I pass out. I'll post one for now - first time on the ground in a while wearing new shoes.

Stock oilpressure gauges are notoriously poor gauges. If I really wanted to know, I'd run a mechanical oilpressure gauge....(oh, wait...I did).
Also, take the valve cover off and see if you have oil coming out of the rocker arms while running.
When I seat the dizzy, I put all my weight on the dizzy cap while the engine is turning. You can feel it settle down that last 1/4 inch..
Next is to fine tune the idle speed and the timing, so that it idles just right.
 
Pighead - thanks for the info. One quick question - should I be able to see oil coming from the rockerarms if I'm using an electric drill to spin the pump, or would that only happen when the engine is running do you think? I will look into a mechanical gauge too.

I was able to get it running and even moving under its own power this afternoon - a nice milestone. I didn't make it around the block as the oil pressure is still possibly an issue. I'm hoping I didn't run it too long in my excitement at just hearing (and smelling) internal combustion. I think there was either some twigs, mouse poop, mouse remnant or some combo of all on the header/exhaust manifold because as soon as it started up and got hot, it smoked & smelled like BBQ - not good BBQ though!

I ran it just long enough to do a quick initial timing adjustment - but I've got a ways to go I think. I didn't want to run it any longer w/out settling the oil pressure issue for the good. BTW - Pighead's static timing method worked great at getting it to fire up and run long enough to run around and start shooting w/the timing light and rotating the distributor.

Oil pressure - once again, I was able to get the gauge to register just under 1/2 by turning the key to the "ON" position and using an electric drill down the dizzy hole to turn the pump. When I started the engine today, the gauge hardly moved - if at all. As I said in my previous post, I took A LOT of time making sure the dizzy was seated in the oil pump gear before and during the starting procedure. I could still have missed though and I'm planning to do some more checks and measuring next, before running the engine again. I'm also wondering if the issue might be electrical as there are definitely some electrical issues that need to be sorted out. I plan to check that too.

I noticed that the Temp gauge did not budge either.

Can anyone tell me what I might expect the voltage on a multimeter to read if I look into the volts coming from the oil pressure sender and comparing them to what the gauge should read? Is this a rational way to check the electrical function of the gauge? Also, is there possibly an electrically related issue that is NOT present when I'm turning the oil pump w/a drill vs when the engine is running? There was a light that stayed ON on the dash gauge when the engine was running - I think it was the Charge Warning Light. I did not look into this further yet.

Some good, some bad, but all in all I was glad to hear it run this afternoon. I had planned to take a slew of photos and even a video of the first start up, but alas, I did not. It was cold as heck today and I was moving forward at a decent clip because we're supposed to get 3'-5' of snow between tonight and Friday. We'll see if that actually happens! I will definitely take some soon though as that's always my favorite part of reading other people's threads. . .

Just one more to add tonight of the newly recovered front seat - which already has dog prints on it! The rear was redone too. Certainly one of the bigger line items on my budget list, but I think worthwhile as the guy did a great job and it's one of the main "contact" points between passengers and the cruiser. It was still cheaper than buying new foam and covers from SOR & doing it myself!

One quick question - should I be able to see oil coming from the rockerarms if I'm using an electric drill to spin the pump, or would that only happen when the engine is running do you think?


The oil to the rockers has to go through a hole in the cam bearing before it gets to the head. So there are two spots in the rotation of the cam where the holes align...it is possible to get lucky and get oil out the rockers without the engine turning but much easier to check with the engine turning over.
I think the oilpressure sending unit voltages are listed in the FSM...probably somewhere here on 'Mud too. A bad ground to the gauge cluster might explain it.
Just plumb a mechanical gauge, even temporarily, in the engine bay, to make sure you're not going to ruin something.
 
So he could run the oil pump with the drill and have his wife bump the starter with the key to see the oil reaching the top end, eh?

IIRC, there is a physical "stop" on the dizzy to show when it has been fully seated. I'll go back to your pic and try to circle it of I can.

Congrats on getting it fired up!
The mouse BBQ reminds me of the movie "Never Cry Wolf". Ever seen it? Just watched it with my little guy last night.

Or leave the dizzy where it is and just use the starter motor...
 
I bought a mechanical oil pressure gauge this AM to install but am having a slight issue w/the fittings. It's all 1/8" NPT, and I bought a "T" fitting to install in the block so I can keep the original sender and just add on the mechanical one. It seems the original electric oil pressure sender will thread into 1/8" NPT fittings, but the 1/8" NPT fittings will not thread into the hole in the block - they are a gnats butt too big. What's the best path to follow here? Find a specialized fitting or tap the block to accept 1/8" NPT?

Thanks,
Tom
 
The stock oilsender threads are really, really close to NPT...I just run the NPT tap in & out a few times...

with grease on the tap to keep any small metal shavings from going anywhere inside.

They are VERY close. I did some more searching and found that the OEM Oil Pressure Gauge is 1/8" BSP, which is just slightly different than 1/8" NPT. As I mentioned above, in stock form the 1/8" BSP gauge will thread into a 1/8" NPT hole just fine. But a 1/8" NPT adapter will not directly thread into the 1/8" BSP hole in the block.

I wussed out and ordered an adapter from my FLAPS - should be here tomorrow AM so I can keep moving forward.

This is the main reason I wussed out. I didn't feel 100% confident that I could run a NPT tap in/out of the hole and catch ALL the shavings and not mess up the threads. The consequences of messing up the threads are pretty big so I decided to wait for an adapter. For that matter, the consequences of having some shavings floating around could be big too I suppose.

Hopefully the block and stock sender really are 1/8" BSP! If they are, I should be good to go.

Hopefully more tomorrow. . .
 
Tuning the Carb?

OK, Back w/more info. . . and some more questions.

I got the mechanical gauge installed and working. I also fiddled w/the dizzy to make sure it was fully seated in the oil pump slot. I confirmed it was by cranking the engine w/the +12V from the coil removed, so the engine couldn't fire. So, the dizzy appears to be fully seated as I get oil pressure when turning the engine over.

So my goal this AM was to do some carb adjustments. It started fine, I timed it so the brass ball is between the pointer and the lower part of the window (don't know exactly why, but I read enough posts in the 40/55 forum that mentioned it, so I did it).

It idles great , nice & smooth, but after warming up it starts pissing coolant out of the radiator overflow for a bit then stops. Is this from having it too full?

I am trying to tune the carb using the Lean Drop method I read about here and in the FSM. I have a vacuum gauge hooked up to to the brake booster hose and the timing light set to read RPM. I started w/the the idle mixture screw screwed out 2 turns from fully seated. When I turn it in either direction however, there is generally no change in the idle at all. I can screw it all the way IN and nothing happens. This doesn't seem correct? The vacuum gauge needle is flickering a bit but doesn't change much either. What am I doing wrong?

A few other notes:
1. The fuel level in the float bowl glass looks to be on the high side - like just about at the top of the glass.

2. As the engine warmed up, the oil pressure dropped. I expected this as the oil gets warmer, but it seemed to drop quite a bit. No leaks as far as I can see.

3. The idle speed screw is backed out so it's not even hitting the carb linkage, but the idle, while smooth, is steady at about 800 RPM. The only way I can drop it is by adjusting the timing. . .

Could this be pointing to a vacuum leak? I replaced all the small rubber hoses in and out of the emissions box. I have not replaced the hose from the air cleaner to the top of the valve cover or the hose that goes across the top of the engine to the carb spacer (sorry, don't know what that's called).

Thanks for the help!

Tom

Now that you have gauges, tell what the numbers are...how much manifold vacuum are you getting at idle? How much does your oil pressure drop?
Your throttle linkage may not be allowing the carb to be on just the idle circuit, which may account for the idle mixture screw not working right. Time it with the BB in the middle of the window for now. Also disconnect and plug the vacuum line to the dizzy when timing it. It's probably time for more pics of your carb, dizzy and vacuum lines now.
Water coming out of the radiator is normal as it heats up...do you have an overflow bottle on it?

Pighead - first off, I want to say thanks again for helping me troubleshoot - because I am an idiot. And I know from experience that it can be frustrating trying to help someone who has limited knowledge. . .

BTW, the overflow bottle for the coolant is my garage floor at the moment, followed by some cursing and a bucket. The overflowing seems to have stopped thankfully.

I took some pics, gauge readings and notes and most importantly have experienced some success. It seems my ignition timing was off. I think I timed it to a piece of dirt or something on the flywheel and not the brass ball. . . that'll make a difference!

Anyway, once I got the timing closer and adjusted the carb linkage a bit, I was able to play w/the idle mixture screw. I was only able to get the RPM to increase 20-30 RPM by playing w/it, but I followed the procedures and after much back & forth between the timing light, idle mixture screw and idle speed screw, here's where I am at the moment:

Idle = 660 RPM
Manifold Vac. @ Idle = 15 (not sure the units)
Oil pressure @ idle = 5-10 psi
Brass BB timed to the middle of the window right at the needle.

The oil pressure is worrysome to me - 10 seems awfully low. I took off the valve cover and ran the engine. At idle, there are very slow drips from the rockers. The ones towards the front seem drier that 4-5-6. I don't have any reference as to what normal is. . .

With success comes another issue/question: I drove it around the block and while it had great power, there was a hissing from the brake booster. I could make it change or disappear altogether by stepping on the brake pedal a bit, but when I lifted off the pedal, the hissing returned. I'm assuming this means the diaphragm has a hole in it and needs to be fixed?

Here are some pics starting w/the carb:
