Hey There I'm curently running a 49cc engine (unknown make) on my 26inch bike. It has a champion spark plug and thats about it, Its been good and reliable from when I got her 3 mounths or so ago.. in the last fuw days its been cutting out at highish rpm like you hit the kill switch and than you have to wait 20 secs or so an she fires up good for a good 30 secs or so or untill you get up to high rpm ??. Ive cheakd the spark its fine and Ive pulled apart the carby twice that was allso fine.. this might of started when I put 98 octane in 3 days ago..Ive draind it all out and going to try 91 again tomorro hopefully shes all good again =( any help would be good thanks Josh.
