I have a 18 HP B&S on a riding mower. Fuel got in the crankcase & on top of the piston. I took the solenoid fuel shut-off from the carb. & put a plug where it was. I don't get any fuel in with the oil anymore, but still do on top of the piston. I put a fuel shut-off valve on the fuel line & run the carb. dry when I'm not using it for a while. My problem is when I forget to shut fuel off & run carb. dry. The engine won't turn over, so I take the spark plug out & blow out the fuel, then it starts. Before I get a new solenoid, (I really don't like them), could I lower the float in the carb. & stop fuel from getting in the combustion chamber? Thanks for any help.

You need a new needle valve (and seat, if it has one). Plus an oil change. The solenoid valve is not the problem; it's only there to keep fuel from going through the jets after the key is shut off.
Yes, IMO don't try fiddling with the float setting which is matched to the power requirement of the engine/load. If you reduced the level the engine would starve and cut out under load.

Thanks for the answer. For some reason I thought the solenoid stopped fuel from going in the bowl & the needle & seat regulated the amount of fuel in the bowl.
