    i have a starfire 70 cc engine and i have had it for about 2 months now i ran it in the bike was running perfectly and all of a sudden one day it just wouldnt rev properly, even if the bike is started and staitionary and you go to rev it it will rev up and then go to a flat dead spot. ive tried everything ajusting all the clip positions on the carby.trk with no difference ive taken the carby apart and blew everything out with the compressor with still no luck. the engine is still like new so it is really doing my head in i use the bike in a daily basis to get to work but at the moment i cant,can anyone help me i would really appreciate it

    Welcome to the forum glad you joined us. Does it rev up better if you run the choke like 1/2 or 3/4 closed?
