Sled is an 05 Early release Renegade w/ ~3.2k. Stock motor w/ an s6x kit. Haven't has this problem before w/ the sled not starting on the second pull, always starts on second pull. So we were up at the hill this weekend and it took about 10 pulls to start the sled. That wasn't a huge deal(just thought it was plugs), but now every time I put it into reverse it stalls, when the seld is warmed up etc., always stalls. Been having this problem a little last year and beg. of this year, but it was few and far between. The sled still runs good, still has excellent midrange. It's def. not the plugs, they were a nice gold-ish color and I even switched to another new set. I can only guess it has low compression....and needs a rebuild! I got the 2 yr. warranty, btw. Just wanted to hear some of your opinions....Ima gonna have to go grab a comp. tool off my buddy. What the proper way to conduct the test and what rnage should the engine be within. I'll post back up tom. w/ some numbers.
