700 grizzly hard start. Please help

My sons 700 grizzly has a very hard start everytime and I'm out of options besides blowing it up. It runs fine after it starts and it will always fire up but it usually cranks a long time,spits and pops out of exhaust before starting. Cold sometimes starts a little better but pretty much the same cold or hot. Things we've done.

Compression "completely new engine"
Checked all electrical wiring
Stator checked
Fuel pressure
Valves many times*
Swap computer with known good one
Swap throttle body "complete"
New battery
Checked tps
New coil and wire and plug*
( All stock except it does have a warrior riser snorkel kit and k& n air filter)*
Thanks for any help
