Hi, thanks for the donation. If you take the coil wire loose from the cap and hold close to engine ground, engine cranking, can you see a spark jump.

Engine cranking, does the rotor turn? All battery cables and engine grounds, ok?

after rechecking i find a very weak spark . i removed the coil and checked resistance per the manual. secondary ok, primary slightly out of spec 1.3 vs 0.96-1.18. is this critical?

A weak coil is a possibility, plus the other suggestions. Sorry about the late reply, I've been having problems with mail.
