consider a thorough carb cleaning. i had always "dunked" mine for 12 hrs. besides with winter upon us, youre not under that much pressure.

Oil Change and Carb clean is part of the plan already. I'm hoping that is all that is needed. This "dunking" you describe, I assume it is something beyond the normal disassembly, carb cleaner, reassembly, no?

Yea, it's great to have 2 bikes and all winter to work on this. The old one runs great and if I find a window with good weather it fires up and answers the call. My GF wants to take a refresher course before riding, and those aren't offered until spring anyway. I'm lacking motivation right now though because it isn't a heated garage. I'll have to do something about that if I want to get anything done between now and spring.

I also found it won't run with the petcock turned "on" only when it is on "Res." When i do the carb, I'll check for blockages in the fuel lines and make sure they're hooked up correctly.
