Sled has ran perfect for me for the last 2 seasons. Last ride, it would have the odd bog & backfire that i assumed was from sucking in the super fine powder we were in (i havent siliconed the headlight adjuster yet). monitored temp constantly and never saw more than 127deg. sled started fine all day and still seems to have good compression on both cylinders. after stopping for lunch it started and ran fine, we took off and i made it about 3/4 mile and it went down to 1 cylinder and the check engine light started flashing. pulled the plugs and pto side was good, mag side was white. still assuming it was moisture, i added isopropyl and left in in the heated shop for 2 nights. still will only run on 1 cylinder. has new plugs & good spark, and mag side plug is wet after starting. im lost with the CFI, where do i start?
