Hi guys; I recently finished mounting my new Chinese Bike To Motor kit on my Huffy mountain bike and it looks good. I fueled it up, put the choke on full, twisted the grip a bit open and I pedaled away, dropped the clutch, the engine turned over and popped and died. I then opened the choke, and then tried this several times more with the same result. When I regained my breath, I noticed fuel residue was dripping from the muffler, so I think that it was getting fuel okay. I noticed that the supplied Chinese spark plug has about 1/2" of reach, and I can see the threads in the head have a lot more thread then the spark plug have. I am thinking about trying a longer reach spark plug to put the spark down in the combustion chamber being careful of course, not to hit the piston. I would have tried this today, but the bike is up at my son's farm at the moment. In the meantime, I am thinking what else I might do. One thing, will be to put a "O" ring in the carb to manifold connection incase I have a air leak there. I have not read anywhere where anyone has had a problem with this engine starting and running. I would appreciate of your suggestions on what my problem might be because I want to ride!!! Regards, Karl
