  1. Unfortunately we don't sell those connectors separately, Briggs only supplies the wiring harness. You should be able to find connectors at an electrical or electronics supply store.

  2. Probably the best step-by-step video I've seen. You know your topic and you know how to say it. Very nice.

  3. OK.. How do you replace the plug wire on this type of coil? The coils last forever, at least twice as long as the plug wire does.. Any junkyard will have an unlimited supply of good plug wires.. they are more than happy to give them out for a buck instead of $20++ for a new coil.. There's plenty of videos to replace the plug end, but not the magneto end..

  4. If the card is not available a standard business card can be used in its place to properly gap the ignition coil.

  5. Replaced coil because no spark after last mow job. Still have know spark. Driving me crazy. How do I check ignition coil off engine?

  6. i have been mowing my lawn without issue. pull it out, and nothing. i worked out my oblique muscles pretty good trying to start it. it did twice for like 5-10 seconds then cut out.

  7. Used your video tonight to replace my ignition coil. Awesome video, great instructions. Can’t thank you enough!

  8. I just finished fixing a problem that drove me wild for a few days. No spark….hmmm. Removed the cover. Cleaned the coil where it mounts to the case with sandpaper to ensure a good electrical connection. I also sanded the flywheel until it was clean and free of dirt and rust. Reassembled everything and still no spark. Being it was only a flywheel and the coil I assumed the problem was the coil. I ordered the OEM Briggs coil from Amazon ($30). I installed it and still no spark…aaarrrggghhh!!! I finally had an idea that I hadn’t thought of…..disconnect the grounding wire that is attached to the little tab on the coil. I pulled that little spade connector off and reassembled the cover and viola. It started and ran. I couldn’t believe it. I chased this problem for days only to find out that the safety mechanism that grounds out the spark when the handle is released was the cause of the problem. It was permanently disabling (grounding out) the coil whether the handle was pulled in or not. Moral of the story…..when chasing a no spark problem and you’re down to the coil disconnect the spade lug at the coil in order to omit that as a possible cause.
