I didn't have time to do another compression test but I will.
However, once it started after using the primer bulb, it would stall after running for a minute. I would prime, start, run til it stalled continuously. Next questions or advice: Should I change the vro pump which mixes the fuel and oil? It's not a cheap part but i don't know if there is anything else I should troubleshoot or test first. it has all new fuel lines and fuel filter.
Thanks again

I suspect the VRO/Fuel pump might be bad based on your description, BUT low compression on the cylinder that provides the pulses to operate the pump may be the real problem. Check compression again very carefully before spending any money on the pump.
