Why would a 90cc Polaris (2 stroke) continue to foul spark plugs.

 

Improper jetting.
Unless the child is not opening the throttle enough to keep it blown out. [img]i/expressions/face-icon-small-smile.gif[/img]

 

my kids pred 90 eats plugs also, and has a stock pipe and jets. since ive taken the electronic governer off it seams to be cured. i hope your right about opening up the rpms and keeping it from loading up, even though plugs are cheap its still a nuisance.

 

same exact promblem i just put a CDI on it and it just kept fouling plugs... what size jets do i need and where do i get htem and for how much? THanks
