Just looking for some opinions on issues we are having with a Carl's 660 sled. It's a 2012 that a buddy of mine bought a couple years ago. At about this time last year he squeaked a piston but we attributed it to cold seize because he wasn't very good about warming it up before taking off. So it had a new piston put in and it ran the rest of last year. Now this year it wasn't idling quite right, it really wasn't last year either, so I checked the tps and the idle was set right from the dealer but when I checked the base setting it was at 0.86 which explains the idle problem. I set it at .70 and set the idle at .94. It idled great but would not go into reverse, it would just die and not restart when the button was pushed.
So the compression was checked and it only had 80 lbs on each cylinder. After taking the top end off we found both of the Pistons to be scored. He said it had been using the same amount of oil as his 800 so I'm just looking for suggestions as to what you think could be causing this after only 4-500 miles.
