Kohler 17.5 Carb. problem

[Rick2912]

Hi My lawn mower will start But then the engine Races and run's at full blast no matter which position the throttle is in.

Any Ideas

Thanks Rick

Is choke functioning properly and is throttle plate wide open at low throttles?

 

[Rick2912]

Yes I think so could it be the solenoid on the bottom of bowl ????

 

[Mikel1]

I take it your talking about the anti- after fire solenoid. No, it wouldn't cause this problem.
So yes on both questions or just on the choke?

 

[Rick2912]

Yes there only one way to connect the metal rods to the carburetor
But when I start it roars and sounds like it going to blow up it used to run smooth

Understood but it has to be controlled by someone or something to stay open. I would check the linkages, springs, cables and also manually check throttle plate movement. If there is no binding anywhere and all is operating normally then it may be the governor.
