Sounds like a timing issue.
Have you checked the flywheel, keyway and crank?

Will it run when primed?  Do you have a know good ignition to swap onto the saw?  145psi is normal for these saws and plenty of compression to run well.


Is there any play in the bearings?

WAG: have you checked seals etc for leaks.

Did you figure out why it needed rebuild (what had caused problems in first place). How was it running before you pulled it down etc.
