I know this should be simple, but I seem to be having a brain fart. I have a 16.5 OHV motor with the fuel shutoff solenoid at the bottom of the carb float bowl. I have this mower wired according to the diagram that Fearlessfront posted on here. I've wired a couple engines up this way and had no problems. I just need to know where to wire this solenoid, it has a black wire and a white one. Thanks for any help guys.

i think the black wire needs to be grounded somwhere and the white connected to a power source

That makes sense. So I'm guessing the white to 12V when in the "on" position, which on my wiring actually turns the coil wire off, or open. I may need to wire in a separate toggle switch for this solenoid.

yes it would have to be a 12 volt source that is only live when its turned on

I wonder if there is a toggle switch that would serve for both things. To run the mower in ON I need to disconnect the ground to the coil and connect the pos. to the solenoid.

Well, that was the problem. I ran a jumper straight to the battery and it fired right up. It was too hot today to do much so I'll wire it up another time. One problem I noticed is that this motor won't stay running at a low speed. The clutch is supposed to release at 1800rpm and the engine dies before then. I think the idle is supposed to be around 1250rpm for the ohv motors too, which makes it strange. That doesn't really matter though, this one is going back to a manual clutch anyway.
