Kohler won't stay running
I HAVE A KOHLER CV186-61533 THAT HAS SUFFICIENT FIRE AND HAVE CLEANED CARB, IT IS GETTING GAS IN FUEL BOWL BUT THAT SEEMS TO BE AS FAR AS IT GETS. I PUT A LITTLE GAS IN CARB THROAT MANUALLY AND IT RAN A LITTLE, SOMETHING IS WRONG WITH CARB BUT I DON’T KNOW WHAT. HOW IMPORTANT IS THE SOLENOID THAT ATTACHES TO A JET IN THE BOTTOM OF FUEL BOWL.
The following is based on the assumption that your carb has been cleaned and installed correctly. Your problem is definitely a lack of fuel issue. The solenoid in the bottom of the carb is to shut off fuel flow to the main jet. If it is not working correctly, you will have a problem such as you have described. An easy check would to be to listen for a “click” noise from it when the ignition switch is turned to the run position. If no noise is heard then either the solenoid is bad, the solenoid is sticky[can be cleaned], there is not power present at the solenoid when the switch is turned on or a bad gound preventing the solenoid from energizing. If your solenoid is working, and the fuel bowl is full as you stated, then the main jet has a restriction, it’s the only thing between the fuel bowl and the carb throat. The fact that it runs when you prime it tells us that the compression and timing are sufficient. Hope this helped Joe
