A drink for all, Shirley -

Well, the afternoon was spent using the compass, pulling the bars off
(looked like it was there according to the compass technique), and
tracing the ignition wires.

I found the short actually in the ignition wire going from the run
switch to the coil, about 3 inches from the coil. It had gotten
caught between parts of the mounting bracket and flattened with the
insulation opened, thus the short only when the run switch was on.

That was a total pain, but now there are two others, although I know
how to fix them.

First, my motorcycle lift's hydraulics leaked and now the lift is
stuck elevated and I won't be able to get the bike off until I can get
lifting help, or figure how to release the safety catches. It is a
Sears lift. Looks like it needs a new piston.

The second is there was a brown sludge in the gas line, and in the
carb. Cleaned the carb and lines, filtered the gas, put it all back
together, and got NO FLOW through the lines. Drained the tank again,
pulled the petcock and found that somehow the filter was off of it.
Found it on one of the benches. I wonder what bozo put the petcock in
without the filter........(guess it was me since I built the darned
thing...how could that have happened!?)

I put a followup pick on the other newsgroup.

Thanks for the help!

Ken
