Rhino won't start

Hi guys I just bought a used 07 rhino 660 with 1000 miles. Been sitting for a while. I cleaned the carb, changed fuel filter , cleaned air filter, I checked spark and it sparks. So cranking over it's getting fuel but it just backfires and won't start. Is there anything electrical I should be looking at. I feel like I'm missing something simple. The timing should be fine I would think only having 1000 miles. Thanks for any suggestions

Kinda sounds like cam timing may be off? You got spark, you got fuel, you gotta have air so something is affecting spark timing based on your description. Any history from previous owner?

Bought it from old guy who got it after friend died and inherited it. He says it ran great then was pulling a trailer which hit a tree and stopped the unit. Then said the fuel pump wasn't working . That's all he could tell me. I just don't see how timing could be out with such low mileage. Could the coil be weak or fuel pump at fault?. I added a primer bulb to get fuel flowing from tank

Is the backfire through the exhaust or carb? Todd, what's your opinion on this?

So I checked valve clearances at TDC all was good. I also did a compression check and am getting about 155psi which I believe to be good. I ordered a new CDI hoping that could be the problem. Anyone have anything else it could be. Cranks over and over won't fire.

I'm thinking timing also, hence sitting for awhile and smacking a tree.
