    I would drain the fuel bowl to get an idea of the float level setting. In other words is there just enough in the bottom to keep it running, or does it seem like enough to not have an issue. If it's getting too much gas it should start running rough and black smoke should be coming out of the exhaust.

    If it was mine, I'd check the point gap and timing again before getting deep into guesswork.

    Yes. Float level is correct

    Somehow locked out of my original account, so I re-joined.

    In the meantime I ordered a pressure regulator as the jeep is blowing smoke out the exhaust. I'll let you know if that solves it for me

    That would depend somewhat on what color the smoke is. Black would be fuel, blue is oil, white/gray is coolant.

    I'm running a Solex on my CJ2A and have a Mr. Gasket fuel pressure regulator. I really need to put my fuel pressure gauge inline and see what it's actually putting out but I have the dial set to 1.5 lbs and it's fueling great.

    Thanks Downs. I hope the Solex/regulator solves my problem.

    I'm stumped in the meantime. I cleaned my Carter YF and put it back on while I wait for my regulator to arrive. Same symptoms, starts and will only run if I keep pumping the gas pedal to rev it, then eventually sputters out. Kinda hard to tell what color the smoke is, seems dark gray. I checked the bowl level after and it is about 1/2 full, not sure if that is just because of the displacement of the float.

    Thanks all for your help and patience, I'm new to doing my own wrenching

    That being the case, be aware that a logical diagnosis needs to begin from known base-lines. And a Factory Service Manual (not Haynes or other generic.)

    Thus, a "by the book" tune up of points and timing, a good set of plugs properly gapped, a fresh condenser, distributor cap, and cap would be the place to start. Anything less and you'll be chasing your tail.

    It is not difficult, just work step by step and be patient.

    Good advice. In software development folks used to say 'RTFM' - Read The F*****g Manual

    I replaced the fuel filter, fuel pump, spark plugs, wires, coil and carb - with the Solex and fuel regulator, but finally took it to a mechanic the past week. Apparently the only part I didn't replace - the electronic distributor went wonky since he put my old points distributor back on and - bam - runs like a champ. It now runs really well and the Solex was a bolt on not needing any tuning or adjustment. I might try taking the fuel regulator off to see if it is really needed, I'd prefer to have fewer parts than necessary on the Jeep. The electronic distributor ran fine for about 3 years, so not sure what happened to it. Anyway, hope your Jeep problem got resolved, too

    "In software development folks used to say 'RTFM' - Read The F*****g Manual"

    Worked in software development for 45 years but never heard that particular acronym, must be a Canadian thing. :D

    This is a good example of why I prefer a good breaker points ignition over electronic. If quality points and condensers are used and everything is set up properly they are reliable, and easier to diagnose and fix even way back in the boonies. I keep my Jeeps in good tune, and not much can go wrong with a points distributor, that can't be resolved quickly.

    I used that phrase quite often with my helicopter flight students...

    I wouldn't do that, it is supposedly really needed on the Solex. If it runs fine now why tempt fate? :)

    X2 on this. Mine runs like crap, dies at full throttle, or floods unless it gets EXACTLY 1.5psi of fuel pressure. The mechanical fuel pump puts out at least 3psi so the solex NEEDS the regulator.
