upstate yank 219 #1 Posted April 7, 2019 well here i am again with another issue as my b-80 will not start after mowing the yard the other day which on my last pass the deck belt broke ;so that is no big thing as i have a spare 'so i decided to give it a good bath well after drying out after a few hours of sitting in the sun i went to start it ;sure it spins over but again it won't start 'so i changed the coil which came off a working 8 horse plus the condenser and plug ;still nothing ;i did clean the points with a file and with the test light there is power on the positive side of the coil plus turning the key to the start position the test light did light up plus i checked the solenoid again power on both terminals ;so what am i missing here ;any thoughts i sure would appreciate it'thanks guys Share this post Link to post Share on other sites
pfrederi 17,147 #2 Posted April 7, 2019 do you have a spark plug tester? Could be bad plug or water in the plug wire 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,495 #3 Posted April 7, 2019 Try the test light on the (-) side of the coil. As the engine turns over the light should flash on and off. When the points are open light ON. When the points are closed light OFF. If you have a steady light the points are not making electrical contact when closed. If no light at all there is a short in the wire going to the points or the points themselves are shorted to ground. Moisture could cause this so leave the cover off so they can dry out.

It needs to turn on and off whilst cranking to give you the high voltage from the coil. Share this post Link to post Share on other sites
