This is the best of all places to ask I guess, I'm trying to fix my friends' polaris trail blazer 250 2 stroke, I can get it started with the pull start, for some reason its a total biotch to start with the electric starter, the pull start gets it in a few pulls, but it will idle fine for a bit, then start popping and idling lower and lower and then just die and it doesn't want to start back up, I have cleaned the hell out of the carb and put fresh gas in it and cleaned every wire connection I could find on it. I can get it to cruise around my yard a bit, but it will only go around the speed of the average lawn tractor, and it revvs up to normal, misfires a bit and drops, goes back up to normal rpms, then misfires a bit and drops, it just keeps doing this. Any suggestions? this video is of it idling itself out: Polaris' are made so that you can't adjust the mixture or idle speed, its done to perfection at the factory, so that can't be the problem. Will try any ideas pitched. thanks guys.
