I dug my snowblower out of the back of the garage and got it ready for a new season. The last couple of years I'd been having a really hard time starting it and getting it to run smoothly. I've changed the spark plug several times, changed the oil, cleaned out the carb and lines, and it still wasn't right. I kind of figured that the coil was weak (bad?) and causing all of the problems. It's a 1995 MTD brand bought at Sam's Club in late 1995 by a relative who gave it to me about 7 years ago. It's got an 8hp Tecumseh motor. I took it apart and removed the coil. Tried to find a parts place that would have one with no luck. Then, I remembered I saved the motor from my old lawnmower I replaced 10 years ago. The chassis had rotted but the motor was mint, so I saved it. Dug it out and saw that it was made by Tecumseh. I removed the coil but it wouldn't fit the snowblower. The end points were shaped differently because the flywheel was a different diameter. Solution- grind the points down with a bench grinding wheel to fit the new flywheel. I installed it and it started right up on the first pull, even with the old gas in the tank! I ran it for 20 minutes. It ran strong. Put in some new gas and now I'm ready for the upcoming winter season.
