Plug could be fouled, clean it, check it re-gap it .025-.030 or not getting fuel out of the carb into the engine.
I put gas down the carb and try, then in the plug hole and try to start it. Then I start looking for stuff thats not right like the gap between your coil & flywheel, loose bolts at the manifold or carb. Reeds not sealing on the reed plate rubber seals, etc., etc.
the bikes only 1 week old the spark plug is new and it has a nice blue spark the carb i unscrew the screw on the bottom and gas came rushing out so idk if thats good the mainfold is cracked on one half so i super glued it together but i dont think that would be it. do you?
