Hey guys. New here of course. Inherited a 2014 1-owner, adult owned Polaris RZR 900 XP that for some reason has a knock/rattle in it and something keeps hitting the spark plug and closing the electrode. I'm here to get help on getting it going and HOPING it is a easy fix to avoid replacing the engine! Going to be off this weekend if anyone close wants to come help. We are going to the family farm for Thanksgiving on Monday for a week and sure would be nice to be able to take it.
