wheelhorse656 20 #3 Posted January 2, 2011 I have a new points and condenser set for that motor new points and condenser cost $6 a set. make sure the points are gaped at .20 and your plug at .28. just a gusse :ychain: Share this post Link to post Share on other sites

TT-(Moderator) 1,127 #5 Posted January 2, 2011 Have you checked the "kill" wire or switch? Perhaps something is grounding when / where it shouldn't be. Did you change the condenser? Share this post Link to post Share on other sites
420lse 18 #6 Posted January 2, 2011 I Didn't change the condenser. The engine is on a mid 1980's snow blower. Has a 2 safety swiches. Can I bypass the swiches? Share this post Link to post Share on other sites
TT-(Moderator) 1,127 #7 Posted January 2, 2011 Disconnect the ground ("kill") wire at the engine to snowblower connection for "diagnostic & troubleshooting" purposes only. If you get spark with the ground wire disconnected, it's in the harness/switches on the machine. If you suspect a safety switch, test it's function with a meter and replace if bad. If you don't get spark with the wire disconnected, inspect the "kill" wire from the insulated stud at the points to where ever it terminates. These engines are notorious for that wire rubbing against the shield behind the flywheel (or any part of the engine itself) and grounding out the magneto (a.k.a. - a direct short to ground) It could also just be the condenser. :D Share this post Link to post Share on other sites
