If you have 12v to the coil and the other side is grounding when the points close...and you have no spark, thats generally a bad coil. Share this post Link to post Share on other sites

pacer 3,177 #4 Posted November 19, 2022 Was it running when you got it? and has since lost the spark? 1 Share this post Link to post Share on other sites

pacer 3,177 #8 Posted November 20, 2022 (edited) OK, one possibility .... points that have been outside for a lengthy time can be prone to form a ...'glaze?' on the contacts, enough to prevent connecting. If you got a volt meter you can see if there is 'magic juice' getting to the points by hooking it to the conx at the wire on the points and rotating the engine - with key on - and you shud see 12v there. If so, the you may need to get that glaze off. There is mixed feelings on using a piece if folded fine grit sand paper and dragging it across the contact points, some just use paper -- your choice. If you dont have 12v at the points then the coil is either bad or you have a bad conx. Less likely is a bad spark plug or plug wire....... They are set at .020 Edited November 20, 2022 by pacer Share this post Link to post Share on other sites

There was overlap...the generation that only knew points, and hated them...then my generation that knew what they were...then the next-generation who only knows how to push a button on a screen.
