The solenoid that engages the gas engine starter via the throttle (foot-pedal) was very warm during a preliminary inspection. I want to be certain before going into town to purchase parts. It appears to be a multifunction solenoid located inside the eng. compartment and is wired to the ignition switch, battery, armature, and a relay switch,(forw.-rev.)? All the wiring and battery terminals are OK, the key ignition switch checks out OK. I disconnected the (new) battery to de-energize solenoid with no success. What’s next?
