Alright heres whats happening...I had the moped running good...its a 91(I think 91) bullitt. Now my brother went out and decided to use it...he put the choke down and it got stuck down so I took off the little nut and it let the choke down...but now it doesnt run right at all...It stalls very quick if idling...and when I accelerate...it seems like the fuel cuts off and it bogs out and then it will come back and i'll go...when I get into second gear...and when it reaches high rpms in second it bogs like crazy...I lost a considerable amount of speed in second gear...Its acting like theres a rev limiter on it...anyway I took off the carb cleaned that out and put it back on and fixed the choke...but its still doing it...So im pretty much clueless here...it never did this before until my brother put the choke on...thats all he said he did...I dunno tho...I did put my extra batavus coil on it because the stock one was working good...but that was while ago and it worked good...Alright any ideas are helpful THanks
