I need help with my 05 Rhino 660.

A couple of weeks ago the timing chain jumped a tooth on the cam, and the piston tagged an intake valve. Pulled it all apart. The chain was stretched. I replaced the chain and cam and rebuilt the head. I got it all back together adjusted the valves and did a compression test. It's 177 pounds. Then I tried starting it... It cranks fine, but won't start and backfires through the carb. I thought it was a timing issue, so I pulled it back apart to check and it is perfect. It was running great before this. Please help! I don't know where to go from here.

    You might have a bent valve since the piston smacked it.

    Timing is spot on?

    Valves aren't to tight?

    Checked the timing again, perfect. Valves are right. There is spark, but won't turn over with starting fluid. Could it the the stator/pulse coil or ignition coil? Do you know how to test them?

    Easiest way for me to tell you how to check the stator. Yet you can just pull the plug and ground it to the head and see if it sparks. That would tell you the whole electrical circuit is good. If you have spark and it's not popping off then you may have the timing 180 out. When you set the timing was the piston at top dead center?

    There is spark.
    Yes it was. I lined up the "I" mark, and lined up the 2 dots on the cam sprocket to the head making sure the cam lobes were down. I pulled it apart just to check it again.

    Man I'm at a loss here. You have spark, fuel, compression and no running motor. Timing is on. That makes no sense. Something has to be off. You need to do a leak test on the head. It has to be a valve sticking. With it backfiring through the carb it sounds like the intake valve is hanging open a hair. When the head was rebuilt did you seat your valves and check the valve guides?
