    VM22 Mikuni Clone Carb Tuning

    Ok ummm...weird but good news I ran it again today with the PZ20 carb. This time I was able to run it for about 15 minutes until there was smoke. I tried it again, and even after a while, there was very little smoke. I was able to actually drive it and man that thing is FUN. I think I am mostly...

    VM22 Mikuni Clone Carb Tuning

    Alas, it's not over... Today I installed a PZ20 carb that I had laying around and drove it around for a while. After a bit of driving, it started smoking again. Same smoke as before. I unbolted the header pipe and the gasket was dripping with oil. I guess there is an oil problem after all...

    VM22 Mikuni Clone Carb Tuning

    Alr, great news! I put the old carb back on and was able to start it with starting fluid. It ran w/no smoke at all. I guess its not burning oil! I am not sure why the new carb puts out white smoke rather than black, but i suspect that there is something internally wrong/broken in the carb. I am...

    VM22 Mikuni Clone Carb Tuning

    I thought it was a gas screw because it was on the engine side but maybe i was wrong. Anyways I just tried running it again with it all the way out this time and I saw no difference whatsoever. At this point, I think yall might be right that its burning oil, but I'm still not completely sure...

    VM22 Mikuni Clone Carb Tuning

    Ok sooo... I definitely overfilled the oil... There was almost a half of a cup extra As for the knocking, thankfully it was not anything internal. I took off the pull starter and removed the chain and the knocking stopped! The whole exhaust setup (ngl the whole frame) is very make-shift. That...

    VM22 Mikuni Clone Carb Tuning

    Oh shoot! Come to think of it, I believe I might have way overfilled the oil. Whenever I went to fill it up after the crank replacement, I had it tilted up. Honestly tho that might not be a horrible problem... just drain the excess and see if that was the problem! I'll get back to y'all tomorrow...

    VM22 Mikuni Clone Carb Tuning

    Ok so a little while back, I replaced the crankshaft because it was originally tapered on the clutch side. I made sure to torque all the bolts to the correct spec. While I was in there I went ahead and removed the governor. I thought that knocking was the flywheel and the blower housing, because...

    VM22 Mikuni Clone Carb Tuning

    Ok heres the update... I tried running it for a while and the smoke persisted. Even with the idle screw turned all the way in, it wont idle do to how rich the mixture is. I need to hold the throttle for it to run. As for the spark plug, it was very black and when I rubbed it on something it...

    The fuel is gravity-fed. I am almost certain this is a carb problem, because it ran perfectly fine with the original carb. This afternoon I'll try what Whitetrashrocker suggested.

    VM22 Mikuni Clone Carb Tuning

    Hey y'all, this is my first time on this forum so I apologize for any mistakes I make... I recently got a GX200 clone engine from a generator that I put on a homemade minibike frame. I needed a new carb, so I thought I would go with a VM22 clone. Now it is running incredibly rich. There is tons...
