Or, after doing the valves, I had everything back together except the gas tank, cranked it over a few times without the Igniters to get some oil up into the valves (and make sure nothing went CLUNK!), then put the Igniters on, and fired 'er up. Or tried to. Just kept turning over, but no spark. Panic about set in, till I looked down and noticed I had forgot to plug the brain box back into the harness. Funny, you'd think the stupid igniters would still have enough sense to fire on their own without having to be told by the brain box!! Geez!
