I have a 94 Polaris 600. It was used when I got it. It fouls plugs so quickly as to take the fun out of snowmobiling. (if that is possible!) I run the sled at about 6000 to 8000 ft elevation. Mostly tree crusing. Some wideopen throttle.
I know it needs to be rejetted
Question: I don't want to spend a fortune on jets, Is it safe to drop 2 jet sizes from where I am. And then if that doesn't fix it, drop 2 jet sizes from there?
If the engine is running lean, will the temp light come on before I have a problem?
