2006 raptor 350

Looking for some help. I bought a 2006 raptor 350 for my wife. It had a bent frame so I pulled the motor and had it repaired.


I put it back together and the it would not run.


I had it at a small shop and the mechanic told me that the timing was off 180 degrees?? During the time he was trouble shooting it he had to shut his shop down..


Getting ready to tackle this myself so looking for a good starting point or list of things to start checking.
Thanks

Still working things out with no results.. Maybe videos will help with getting some suggestions.


Also bought a compression tester the pic with 65 psi is with the throttle closed. With the throttle wide open she's getting 120 psi..
