I have briggs & stratton 21 horsepower 385700 series engine that dumps gas on the plugs killing them. sometimes they will sut up. seams to happen when govenor kicks in. it will do it some times when you start the blades.
seams also to happen when it hot. last sat. it killed the sparkplug in the l/h cylinder, when i changed
out the spark plug it ran fine until i started up the blades then it killed the r/h plug. this sat. it cut
without a problem. any ideas what my problem could be. it has been doing this for a couple of years.
sometimes when i change plugs & air cleaner it will be ok for a while.
