im stumped

Ok, i am having a heck of a time trying to figure out what is wrong with my 2007 660 rhino. I was driving it through a field and it suddenly lost power. It didnt stall right away it just wouldnt pick up speed. I shut it off and now it wont start. it rolls over fine and backfires but wont start. I called a local dealer and he told me that i probably burnt the valves. I tore it down and the valves are fine. The piston is in good shape and the cam looks good. Im trying to put it back together now but dont know how to set the timing. if anyone knows how i would really appreciate some feedback on how to set it. Also if anyone has any ideas about what could be wrong and why it lost its power i would really appreciate any help you could give me.

WOW.... You tore the motor apart without checking the easy obvious stuff first????

1. Clogged fuel filter
2. Bad CDI

Many other things to check before pulling apart the motor.

Pull the gas tank and on the side of the motor where the fan is remove the fan and there is a black threaded plug remove it w. A screw driver and use a flashlight to look in the hole u will see alighnment marks inside line them up by turning the big bolt that was underneath the fan also the cam has 2 dots that need to be horizontal with the head the dots are on the gear down toward the bottom on each side good luck brminc

Also on the flywheel there are 2 marks...Without looking at the manual I believe TDC is the "I" Mark
