Jeez, I hate it when I say I'm sure of something and then have to take it back.
When I do it with the wife, I never hear the end of it. But then, she does it
as often as I do, I'm SURE.
I just looked closely at the valve rockers, and sure enough, the ones at
cylinder #1 are set for exhaust. I'd been seeing them all afternoon, convinced
they were both closed. Ah well, I learned that distributors are made to be
inserted into the slot only one way. Now I'm faced with the original problem
of getting the old girl started. The spark looks good and strong at all 4
plugs, so I guess I'm getting into the carb again.
Thanks for the good advice and explanations, and here is one more question.
How do I get an approximate static timing setting with the Lucas electronic
ignition. Do I align the little pick-up arm in the distributor with something
when I have the crank set where I want it (probably at 10 degrees btdc)? On my
TR6 (with points), I know how to do it with a test light. Can you do that with
this electronic setup?
Thanks again,
Tim
