Hey guys so this is my second build, I had a 80cc engine on a 90s mountain bike which ran perfectly no problems and did me well for about 3 months, the motor was fine but the bike itself had gave out, now I have transferred the same motor to a beach cruiser and to my dismay I can't get the damn thing to go for more than a minute without bogging out, ive already took apart and cleaned the carburetor installed brand new fuel lines Cleaned out the filter in the gas tank so fuel flow is probrabrly not the problem, I've cycled through different settings on the jet needle with no luck, I also am using a brand new spark plug , I checked the wiring on the spark plug cap and cdi they are ok, I'm really lost any help is greatly appreciated
