Last night I changed my points,condensor, and plugs in my 40. Someone along the way put a mallory centrifugal advance distributor in and took out the electronic setup. I would like to slap that person. Anyway, I gapped the points at .019. Last night it started hard, actually flooded. But once running it ran great. Then this morning ,same thing. Go to leave for lunch and it won't start. So I go to mallory's website and find my point gap should be .022. So I widen the gap a bit (a bit too much) and it fires up, but won't rev over 2 grand. I drive about a mile to napa, buy a feeler gauge (left mine on the workbench at home) and regap the points. Fires up, drives fine. I put the timing light on it, reset the timing, and now it's sputtering slightly under load in first.
Question is: How do I hook up a dwell meter to check the dwell? I have searched and found lots of references to this, but nobody explains how to hook it up to the truck. I have my grandfather's old dwell meter, but no idea how to use it.
