Did you check the compression with the throttle open? 100 PSI is on the verge of not starting and running. Valve clearance can affect compression as well as worn rings. If valve clearance is correct squirt a little oil in each cylinder and check the compression. If the compression does not come up it indicates worn or mal adjusted valves. compression comes up indicates worn rings. Ideally a leak down tester would give better results and easier to use.
