My problem quads are the 90 eton and the 90 polaris, both have the same engines and are having the same problems. Both quads have seen alot of water/mud last season, they both idle good but will not move when given throttle? They chug a little but will not produce power. I have cleaned the air filters,carbs,new plugs, removed the fly wheels cleaned stators not sure where to go from here? Both quads are 2 strokes. Is this possibly a electrical problem? I dont know enough about timing and or stators parts to continue with the trouble shooting. Any help would be great!!!! Thanx

 

by any chance is there an override that is kicking in and not letting it move for safetly? you might want to post thi on the "chinese quad or kids quads" section for good anwsers as well.
