Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Why does the Kohler solenoid 12-757-33-s keep malfunctioning? I have had to replace it twice in the last month.
Hello, and thank you for choosing JustAnswer.
I'll be helping you today.
How have you been testing the suspected bad ones?
One option is to simply not use it and make sure to idle down the engine before shutting it off. Is it freezing in place because of gum or varnish building up?
Not sure how to do without it. If I disconnect it from power, no gas goes to the engine. If I remove it, gas leaks from the bottom of the pump. There does not seem to be any build up whatsoever. Both replacements look shiny and new. However, I flushed out replacement #1 and it now moves up and down. I replaced the blown fuse and installed replacement #1. The engine starts.
I flushed out replacement #2 the same way. It moves only partial up and down. I installed it. The engine started for a few seconds (maybe residual gas from previous start up) and the fuse blew. I again installed replacement #1 and replace the fuse. The engine starts. How long will it continue to start? I'll find out tomorrow when I mow the grass. This seems to be a mechanical problem with the fuel solenoid. Is this a manufacturing defect and something I should be taking up with Kohler?
They are a commonly replaced item, but certainly not to the degree you are describing. I would recommend asking you Kohler dealer to contact the disctributor and see what they will do for you. This is very unusual.
Is there anything about the fuel, perhaps? What brand, grade, and age of fuel are you using?
The same type fuel has been used in the lawnmower for 4 years. BP 87 and two days old. I'll contact the dealer and Kohler.
I think you have done all that you can. Thanks.
