Hello Mech... The explanation and that diagram of the starting system circuits is super helpful... I should be able to trace out the problem lickety split with that. Thanks a million. And thanks also to everyone that piped up with some brilliant ideas for what to check for and test! I can't wait to get back at it!

I pulled the carb back off today, took the throttle plate spring and rubber sealing washer off again, took the one screw out, the one i could get out, started working on the bolt that was stripped. Sprayed lots of Pb blaster in there to try and loosen it up. As i was working on getting the bad screw out, i noticed that it was working correctly, no sticking or binding, turning it by hand. Hooked the spring and plate back up and binding again. So my conclusion is the shaft bushing is bad ,spring is pulling it to one side causing the plate to get mis aligned. Still havent got the screw out i have tried a lot of different things, i think i will try cutting a slot in it but may be difficult it flush with the plate.
