The paint is good at the flange so I don't think it moved.I went out this morning and checked the wiring harness, it has three wires,wht ,red and blk. I assume that the wht is earth and the other energize. I think that the solenoid is a dual coil some thing like you have on hydraulic systems with solenoid controls. When I turn the key to the run position, this turns on the fuel by extending the rod into the governor  linkage,and when I turn the key further it moves the rod even further out.when you cut off power, a internal spring in the solenoid moves the rod back to shut off fuel. The thought I had after I read Butters input is maybe it moves the inkage to advancr the timing and maybe centrifical weights take over after it starts. That little boost from the ether gives it a kick that the starter won't.  Also until I check for current in the harness I haven't eliminated the key switch.I'm just guessing so I'm going to pull solenoid today and check for current in the harness. thanks scott</blockquote>
