Not Starting, No spark

[ILENGINE]

Unplug the solenoid while it is running at any speed, let me know what happens.

On the Kohlers you can full choke cold start them with a failed fuel solenoid. I have seen it more than once in my career. I have even limped them into the shop. As soon as your open the choke they die, but will run roughly on full choke with the solenoid either not energized or stuck shut.

Hello ILENGINE:

I don't disagree with you, and I have used that same process myself when a solenoid fails. It works sometimes and others not.

The other term used for these which is technically correct is "after fire solenoid". After fire occurs when fuel is drawn into the hot exhaust system and ignition spark has been shut off.

Most people use the term "backfire" because it is the most familiar term that has been around and taught for many years.

Thanks for being so argumentative. Whatever.

Put down you juicebox and take a breath guy. Getting all fired up on a mower forum is pretty silly.
