I have a scag STT61V-35BVAC and the mower runs for awhile and then shuts off. I think it may be the fuel solenoid, but I cant find it. Would love some help.....
It resides on the bottom or side of the float bowl if that model has a carburettor engine
Easy way to eliminate it is to either power it from an external battery ( confirms the wiring ) or to replace it with a bolt & O ring or fiber washer .
That engine came with two different carbs available. One with a fuel solenoid and one without. If you have no electrical wire going to the carb, you have the one without a fuel solenoid.
