I have a Craftsman 15hp lawn tractor (917.256544) that ran good up till a couple months ago. We had a clutch spring replaced, and after that the engine will not turn over.
Our first thought was that the clutch safety switch was somehow damaged, so using the wiring diagram we bypassed the switch by connecting the two white wires at the plug. The engine is still not turning over. We also tested the seat safety switch and confirmed it is working properly (when pressed the black wire circuit is interrupted).
All along, when the ignition is turned to the on position, we hear a single light pop near the area of the carburetor on the front left side of the engine. It is a different noise from the rat-at-at of a bad solenoid. There is an electrical component at the bottom of the carburetor, but it is not draw in the wiring schematic.
We can get the engine to turn over by putting a screwdriver between the two main solenoid posts, but it won't fire.
Any insights on what might be the problem?
Thank you.
