I have a lean problem stuck 2 pistons today. I have run this kart for a year and a half at the same track With no problems. jetted for about sea level after first stick did it again After 4 laps. Changed fuel pump checked for leaks. Using t return to tank single fuel pump. Tank has no vent. I Changed nothing since last year. Can someone give me some ideas where to check now. Thanks Ed
It’s not restricted probably shoud be I was jetted 5 more richer than the other 125s. The fuel lines were full but when I revved it on the stand it sounded like a leopard tag. It revved up and down real fast and was high pitched not like a cr 125.
