Getting it road worthy. Whats wrong with the carb.

[LAgallegos]

Well guys, I just took her around the block with minimal smoke!!!! I just bought oil and hopefully tomorrow I can swap it out.
Weird thing I discovered.... I can't find a mark for TDC.... I feel stupid but I've double checked, watched it go round, and there is no mark whatsoever on the crank for TDC. So yeah. Im kinda stumped. She runs good so she's gotta be close but no way to really check.
I'm probably gonna bolt the air filter back on and start working on the brake lines and then she should be ready to go

The PO only had the truck for a week. Super nice guy, mainly parts out fj60s for fj40s but this one was in such nice condition that he wouldn't part it but needed to get rid of it fast so I got it pretty ridiculously cheap. Said the guy he bought it from had it sitting in his front yard for quite a while, which is shocking cause its in really good shape except for some rust. Really haven't changed anything since we bought it and it started right up(except for that idle issue). So its quite a miracle truck.

.... I can't find a mark for TDC....

With the engine off, transmission in neutral, emergency brake on and wheel(s) chocked, slide under the engine and remove the rectangular flywheel cover...you should be able to rotate the flywheel by hand until you see the TDC line and the 7* BTDC BB stamped into the flywheel. Paint them white with fingernail polish so they are easier to see when setting the timing with the strobe light...

Congrats on the first trip around the block! That's gotta feel good!

Well, they way you're digging in fixing things on it and taking responsibility, it's gonna run like a top in no time...

When you say crank you mean flywheel right? The timing BB is on the flywheel. You can see it from the passenger side through a window in the bell housing.

Apologies if this was covered earlier, I went from page two to page six.

EDIT:

Slow left beat me to it. Use his pictures.

My bad, J...I was looking around for a thread where I posted those pictures before to help a guy out who was new to the 2F and couldn't find the timing marks, but couldn't find the bloody thread!!! So I just reposted the same pictures...

If you skipped over pages 2 to 6, you missed the best parts! Action, drama, suspense...part political thriller part American summer blockbuster...

Set the ignition timing so the engine makes maximum torque at it's max torque RPM. This can be determined with: an engine dyno, a chassis dyno, an onboard dyno or a stopwatch.

Set the idle speed to the desired RPM, then adjust mixture screw so RPM/vac peaks. If RPM has gone up, readjust RPM and then fine tune mixture. Repeat as needed.

 

[LAgallegos]

Interesting. Ive never seen it on the flywheel of a car before. Maybe I'm just a noob, but I've worked on a few cars....
anyway. Ya'll gotta help me name the pup!

oh and I threw on the air filter and changed the oil. Wow, I wish all the other cars I've worked on had such an easy oil change. I almost cried.

Thanks for the clarification, Jim. I have neither access to a dyno nor an onboard dyno (like the g-tech pro), so I'm looking into how I'll go about taking the measurements the old fashioned way...I might post up again any 'progress' to see if my logic jives with reality...

That one's all on you, Gallego!

Keep posting up progress/obstacles as you move forward...there's a bunch of knowledge here on MUD!

Looking good dude... makes me want to dive into my carb and get her adjusted properly. I don't have near the problems you do (just running a bit rich) but sure that she could use the rebuild none-the-less.

Just guessing here, but have all the other cars you worked on been built after 1940?

Could be mostly GM motors too....

Okay so i tried to take it on a maiden voyage to get some brake lines and when going up a hill in 3rd gear. All of a sudden it stopped accelerating and the engine just slowly died. I got it to start right again BUT it would just die. Gas didn't matter. I roll started it again and still it won't take gas. just dies. The carb looks fine. But what the heck is the issue

I took it around the block a couple times earlier and it was fine!

Check to see if one of the pulleys on a belt driven component has seized. You can try one of the following:
1) have someone crank the engine over while you look at the pulleys to see if one is not moving, but the belt is moving around it
2) with the engine off (after cranking or running - if you can get it to run for a minute or two), with your fingers, pinch the sidewalls of each belt to see if it is warm/hot
3) with the engine off, loosen the belts and try to turn the pulley on each component by hand

Also, is the fuel level in the sight glass on the fuel bowl of the carb coming up to 1/2 way?

 

[LAgallegos]

It was when i checked it earlier today after my lap around the block.

The battery is toast right now(its old) so I waiting for someone to come jump start it and then i'll check on the pulleys

 

[Slow Left]

So, if the fuel level in the sight glass on the fuel bowl of the carb coming up to 1/2 way, then the fuel pump is probably working OK, the needle valve is probably working OK and the float is probably set correctly with respect to the needle valve. But there could still be something going on in the carb.
With the engine off, air filter housing cover off, if you twist the accelerator torque rod, you should see fuel squirt out in the primary barrel. If not, could be a clogged circuit somewhere.

If the battery is toast, then you must be suspecting that the alternator isn't charging the battery. If the alternator doesn't charge the battery, the truck will run off the battery until there is no more juice in the battery, then the engine will die.

This!!! And don't be discouraged... this is usually how this goes for trucks that are neglected and then suddenly get a healthy ration of "lovin."

 

[LAgallegos]

How do I test if its the voltage regulator or Alternator? I was checking the battery posts with voltmeter and it was defiantly not high enough.

Also, I think I found the problem. I had it again yesterday after fixing a different problem which was the cause for the other day when I was freaking out. I drove for 30+ mins filled it with gas and was just entering back into my neighborhood and it died again. I was checking it constantly earlier and the fuel bowl was always at half. But I checked it as soon as I died and I couldn't tell anymore. I'm not sure if it was full or empty. My guess is full, because I could here it giving gas and the truck was still dying. So I'm think it filled and flooded the engine. Just my guess. My friend says its a sticking float. Opinions?
