If you've used assy lube, pull the fuses for spark & fuel pump. Then, crank till pressure is achieved.
To get start-up pressure (50-60lbs), I had to crank 3 or 4 times for approx 10 seconds each. Afterward, replace fuses, then try starting.
The first time I attempted pressure, everything oiled up just fine, without priming the pump.
More recently, after a rebuild, the pump had to be primed with vaseline, bec the pump was sucking air, & I couldn't achieve pressure, otherwise.
Best of luck with your project!
