Hey folks, I have a 66cc Grubee, NT carb that came with the kit. I ran it all last year plus about 5 trips so far this year. I was out for a ride and all of a sudden lost power and the engine won't even idle now but still starts up. I replaced fuel filter, lines, fresh gas (40:1), spark plug, tried a new muffler, magneto and checked for air leaks on cylinder head, intake and crankcase seal. I do have a damaged throttle cable where it connects to the carb. Will this cause air leaks and might be the problem?
