My lawnmower won't start.


This is a one year old Husqvarna riding mower 20hp Kohler engine and I'm getting fire to the sparkplug and gas to the carb, has a clean air filter. I dropped the carb bowl down, and gas will flow through. At the bottom of the bowl is a small push plunger with a red wire going to it. How does this electrical fitting with a plunger allow gas or no gas?

By any chance did you drain out the old gas and replace with fresh?

I confess, I am using last years gas, but there's something else in the works here. I can take a spray bottle and give the carb a shot of gas and it'll fire up for a couple of seconds. I've used carb cleaner and not a pop, so today I'm taking the carb bowl off and watch the plunger/electric item when I hit the key. And I'll use fresh gas !

For what its worth, the mower is now working. I dropped the carb bowl down and exposed the plunger electric gizmo, or whichmacallit,and turned the ignition key to start and the plunger did nothing,so I seated the plunger and put everything back together.........mower started, replaced nothing. I'm guessing that this electric activated plunger shuts off the gas inside the carb due to a malfunction. (Still used old gas)......sure would like to know the sequence of operation of the gizmo.

there is so much alcohol in gasoline anymore that it really messes with the rubber in a small engine. I use to rebuld them when they got sticky like that but the last couple I have just ordered new carbs online. a few bolts and you up and running.

The mower quit again, and found a local parts place that had the "Qizmo" in stock, which she called a fuel pump, but on the package was called a "solenoid repair kit" which replaces kohler 12 -757-33-s
ch/cv11-16 ....65 bucks ..ouch.....back to mowing .
