    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.

    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...

    VM22 Mikuni Clone Carb Tuning

    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...
