destins 1964 fj40 FST restore thread

[destin]

Hard to say, does it occure at high or low revs?

The miss was happening around 1000-1300 ish rpm wise

I also notice some gunk around the hexed area of the dist shaft ( on the flat spots ) that looked like maybe the dust form the cap or gunk from point arm that hits on the dist shaft.

Gonna clean that off before i reinstall.

Should i spray some compressed air in there? Like that canned air from the computer store? ( my air compressor is in the basement and will not reach to the street.

I had similar issues when my Cruiser had points (283 Chevy). I would run great then it would start backfiring chuggin then die while I was driving, would let it sit for 5-10 min then it would fire right back up go another several miles and do it all over again. Luckly for me I worked for an Auto parts store and the head mechanic for out delivery trucks took a look at it and ran a few tests and found it was the ceramic resistor on the firewall went bad. So we grabbed a HEI Dist installed it, no more issues after that!

awesome.. didn't know you scored that tool kit and you're staying in OR. Nice!

I wonder who scored the latest tool kit on ebay...

Thanks man

yeah i dunno who got the last one looks nice

wednesday i am dropping off my cruiser at Landcrusier NW to have em swap out the stripped thread on the manifold where the carb mounts

Hopefully when that is all done i should be rip roaring

Right now i can see vacuum flutter until it is warm, and some little ones now and then at idle and when i start in first sometimes.


After the engine / manifold is heat soaked it seems to go away for the most part

I keep ya guys posted


here where the power and ignition wires i replaced to eliminate any weirdness from that, man they were ROUGH looking

this is how nasty my min power wires and ignition wires were before i replaced them haha

there where funky splices and wire core exposed, pretty skanky

was the PO Joseph Lucas ?

haha i know right?

Can you believe the splice and twist connector on the main power wire to the fuse box?

jebus!

I might buy some colored wire from cooler man and rewire from the generator to the voltage reg too, just to have fresh wires delivering current to the system

but man, changing the main power wires an ignition even made my display lights brighter!!! headlights etc

 

[subzali]

Don't worry, treeroot in our club has an FJ40 that has twist connectors in it (not his doing though). So you're not the only one

 

[destin]

well replaced the manifold studs and tightened the carb on well ( the shop put aircraft seal between the manifold carb insulator, dunno if that is weird or not )

But the hesitation is still happening, it is like it is not getting fuel or something.

Site glass seems full when i look.

When the engine was all heat soaked I went out and started it and it was idling weird, vacuum fluctuating like like 4 inches of mercury, you have to rev it out and it eventually becomes stable agin, but it is weird as hell.

It is like it is not getting fuel or some vacuum leak?
But it only happens every once in a while?

The manifold made a hot metal ting ting noise that you can hear with the hood open, that normal?

What can cause this weirdness?

Point are good, ignition is rewired fresh, dist is new, new cap and wires, But i do not think it is spark related, has to be some weird fuel delivery problem...

This past summer when I was getting my '70 back up and running I had a similar issue. I had Mark rebuild the carb. A mechanic did the remaining tune up work. I would get it back and it would run fine for a week or so then start cutting out. After a couple times back to the shop it was found the fuel pump was not working properly. Once replaced I haven't had a problem since. Not saying thats your issue but you haven't mentioned anything about it recently. I recall you did some work with it before.

I thought it was the same thing, and i put a fresh new pump in and new fuel lines form the pump to the carb ( bent some steel )

Yeah i dunno whats the deal, sounds like a vacuum leak cuase the vacuum fluctuates even heat soaked occasionally for no reason when i restart it, but i can "rev" it out and it seems fine, the fuel site seems full, fxxxing weird s***, it is like it is working out air in the system, but the site glass is full.

It almost sounds like back pressure off the pipe combined with no fuel.

but if i am idling at a light and go for gas it seems like it does it sometimes ( not all the time )
sometimes the idle will start getting weird and the vacuum fluctuates, then i can rev it out.
Happens sometimes too at certain low rpms ( sounds liek no fuel )

It has to be something simple.

maybe it is as simple as something in the tank lines from the pump to the tank, but why would it do it with the site glass full?

 

[destin]

its weird little hiccup, I just do not get it.

Sometimes the rig diesels when ya turn it off...
i have to have the idle mixture screw out about 4 turns for it to idle correctly ( vacuum at 19 inches when it idles steady and is not acting weird )

Does not look to be running rich from the plugs, but hell, it jsut seems weird.

I have an oil bath air cleaner attached, with the correct amount of oil at the line...

if the air cleaner leaking around the seal or it getting somehow mysteriously restricting air cause this?

Any ideas guys?

 

[destin]

when they put new studs in they put in some high temp aircraft sealant between the carb / insulator and manifold... this cannot be good for the motor right?

Should I pull that and clean that crap off?

 

[destin]

ok took it out for another ride just now, was running great then at a stop light it died on my ( like it was getting no fuel jsut kinda stuttered out ) Look at the fuel bowl, and it is at the line in the site

Cranked with the pedal all the way down a few times and it stumble stutter and started and a i revved it to get it through the light as is stuttered and stubled and i pulled it over left it idling ( idles ok now )

I reved it out and the stumbles started to go away, then drove it home and it ran ok.

WTF

Do i jsut have crap in my tank still from the body shop ( I flushed that tank like 8 times, but body filler dust and sand etc could be still in there, the filter picks up some now and then still )

Is it as simple as me just getting my tank reboiled and relined and running new lines?
Tired of spending money and not getting to enjoy this truck, or even being able to count ion it for big fun trips.

oy!

Aircraft sealants are sometimes used as gaskets in automotive applications. They are similar to some of the sealants Toyota still uses on its vehicles.

All that being said, there are other products, such as The Right Stuff that some people swear by.

 

[waiting for time]

You might want to check inside the fuell bowl for dirt. It sounds like your jets get blocked now and then.

 

[a.greenspan]

Yes, I think so, you have some dirt in your fuel system,
would chance the fuel filter more often.
Buy such cheap plastic fuel filters and chance them often.
When all the dirt is gone, you can switch back to the old school
Landcruiser filter.

x3. Sounds like you better drain your carb and see if there are any floaties (or sinkers ) in your float bowl getting sucked into your jet.

hmm, i am pretty sure it is not supposed to be used on the carb though right, i mean that is where the fuel mixture is going on.... seems like a bad idea if that s*** breaks down atmospherically and gets into the engine, maybe i am wrong, just seems messy and unnecessary..

::shrug::

 

[destin]

ok might pull the carb off again , clean it out again ( pull it apart and blast air and clean the accelerator circuit and the low idle / power circuit ) and replace the fuel filters again...

Might need to have them reline the tank to eliminate that...

kinda a pain in the ass


Thanks guys

Sounds like your running rich to me. Flooding out at idle, sputtery, clears out with rpm.
Not a fuel delivery problem (the carb has gas in it) When a motor goes lean it usually increases rpms then dies in my epxerience (mostly dirtbikes). Not get sputtery and blubbery. Having the mixture screw out 4+ turns seems weird to me. That is usually a sign something is off in your idle/pilot circut. Just tossing out some WAGs.
