I replaced the coil, condenser, spark plug and air filter on my 126 K301 to try and solve the intermittent shutting off when warm problem, I was able to mow twice now without it shutting off. Last night I started it up, let it warm up for a few minutes and started mowing and within 30 seconds it shut off and while it was shutting off I hit the brake and it immediately fired right back up and I continued to mow for 40 minutes without a problem. What else could it be ?
Points, voltage regulator, starter-generator ? When it shuts off it's like someone turned the key to the off position so I'm thinking it has something to do with spark and not a carburetor issue.
