Adjust the dwell with the engine spinning. Dammit you're makin this hard. Loosen the screw so it's snug enough to hold the points in place, but you can still make your adjustment with the screwdriver. Spin the engine watching the dwell meter and adjust to spec and tighten the screw and recheck.
Sorry rusty, not trying to make it difficult man. I've never delt with points so it's a learning experience, we are all dumb in something. I'll give it a shot and see what happens when the storms clear out. Thanks again for your help.
