Running again !!
The injector pump was full of foam, which shook loose every time the engine got a good gulp of fuel and the detonation shock blew the bubbles loose. Then it'd coast a bit, fire, coast. Much like a hit & miss, only more missing. I eventually used a wrench at the injector, and bled air every couple of missed fires, and finally got it going.
I did not pull the Delivery Valve Retainer, it was on awfully tight, and I did not want to wrench that hard on it. I rocked the flywheel back and forth, pumping each 1/2 rotation, and rapped on the side of the pump to shake bubbles loose, when it finally looked good, I hooked the HP line back up, and got it firing a bit, then bled the upper fitting as it ran.
I don't want to run it dry again.
