Well, today I took the injector out and was able to use my fingernail to scrape it clean. Also replaced the fuel filter, and relocated the fuel tank, and installed a foot of clear tube between the return line port and the fuel supply port, as a fuel level sight glass. I assume it will go bad in a year and I'll have to replace it, but being able to see the fuel level is worth a hunk of hose.
Purging the air, was stupidly simple, I hope it doesn't stop on me half an hour into the morning power run. I twanged the new fuel line, bled each connection, and even after shaking all the fuel out of the injector when I was cleaning it, I got dribble at the injector after the 4th fuel pump stroke, and tightened the nut and got Creak right after that. And it started and ran without stumbling.
Valve adjustments tomorrow, maybe before running it.
EGT (Actually IR thermometer gun) this am, after a good run, 325F, which is about normal, at the nipple at the exhaust flange.
