I have the identical Jeep, and I just installed a Howell fuel injection system. That means I have in a pile all of the original fuel system and emissions items that you might need (my '90 was unmolested and running before the fuel injection swap). I was going to put an ad on my local craigslist for the pile, but if you are interested message me privately and we'll see if we can work something out.

I'll be adjusting my carb tomorrow which is most likely the problem. I'll send you a message tomorrow if it doesn't work.

Haven't been able to work on her too much for the past few weeks, but hopefully I have more time now.

Anyway, I couldn't get her started to adjust the carb when I realized there was no spark once again. Went and got a new Ignition Coil and she fired right up! Everything seems pretty fine besides the smoke of death (literally) spewing out. That stuff is killer. I'll try to take her to a shop tomorrow for a Muffler and Catalytic Converter replacement. Hopefully then it'll be good enough to drive around and without dying from the smoke.

I also got bored one day and decided to paint the old rusty rims since it was just sitting there anyway. I noticed after I painted them that the rims in the front and the rims in the back were 2 different types, haha. I dont think they turned out too bad. Next step is to replace the smashed body parts, grab hard doors/top and get a new paint job.

That is good news!

Can you take this YJ for a ride? The cylinders are probably full of fuel. Nothing makes an engine that has been down for a while better than to take it for a drive. See if the smoke issue goes away.

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

I'll try a drive in the morning. Hopefully I can get around the block before passing out from smoke inhalation.

I never got around to getting the muffler/catalytic converter, but I noticed after taking the muffler off that there's no more smoke of death. Now the problem is once again it will not start unless gas is poured into the carb, but doesn't run any longer than 5-10 seconds. I took everything apart last night and completely cleaned everything with carb cleaner. Still the same problem. Think it might be just a bad carb and I should just get a new one? Any suggestions would be greatly appreciated.

Are you getting enough fuel to the carb? Take the feed line off and stick it in a bottle. Turn the engine over and watch it fill up. Should get half a water bottle fairly quickly.

Agreed!

How much fuel are you getting to the carb? None?? Then check out how much fuel is getting past the inline fuel filter.

A tank full of gas over a ten year period will evaporate leaving a glob of crap in the tank. Adding fuel to it just thins that glob out, clogging your fuel system, starting with your inline fuel filter. If you replace the inline filter and can get it started again, only to then run into the no run situation again, I would think dropping the tank and cleaning it out would be a prudent move.

IF you have fuel coming through the fuel filter and the fuel pump but can't keep it running the next thing I would suspect would be the needle valve and float assembly in the carb.

Keep in mind it did fire/run and then quit. Most likely cause is lost a fuel supply.

Yep, also tested that. Fuel comes through the line fairly easily. It gets into the carb, but seems like it just disappears after that.

Seeing that the fuel is coming through the line fairly easily, I don't think the problem would be with the filter. If it were the needle valve/float assembly, what would be the solution to getting that fixed? Or do I just get a new carb? I'm kinda thinking the float assembly is the problem.

When I got mine the fuel in the bowls in the carb varnished so bad it would brake turn over. 20 min cleaning with a a tip and it ran really rough. We ended up re building the carb 100% and it worked for while after it was tuned right.

I cleaned mine out the day before yesterday. There was a little grunk (new word) in the bowl but nothing too serious. At least yours ran, haha. Mine won't run unless fuel is poured into the carb.

Think a rebuild kit would be worth trying?

If not, I'll just try a used one and see if that was the problem.

I think it would be worth a shot. Before I rebuilt mine the fuel would suck back into the line or evaporate and I couldn't get it started if it sat for more than two days. Had to pour gas into the carb to prime the system.

I agree!

This YJ sat for ten years IIRC. That carb probably looks like the inside of an old varnish bucket. If that carb is what I think it is it is a Carter 8383 or 8394 carb.

Can someone chime in to verify that for me? Look for a tag on the carb or other ID stamped into the carb body.

Rebuilding it;

Just one of a million video sources for information like this also
