I tried your method and got a few bubbles out, but very few. The coolant
level was about the same today after I drove it to work as it was a ffew
days ago when I filled it. This morning on the way to work the temp gauge
was in the red again, fans running. Tonight on the way home when it was
about 90 degrees outside the temp stayed normal the whole time. Weird.
Seems I have heard that running with timing too advanced can cause
overheating so I checked the timing and it was running 12-13 BTDC at idle so
that shouldn't be the cause. I finally got around to fine tuning the ZS carb
and hopefully got it tweeked about right.
So we'll see what tomorrow's temp gauge reading is.
Also got around to fixing the interior courtesy light. It's a rocker switch
(plastic) that had broken a piece off that held the moving metal rocker
contact in place. This light is a  $40 Moss part, so I started improvising.
I tried JB welding the metal contact to the broken stub of plastic last
night and it wouldn't hold. Tonight I found some fine wire thread in my
wife's sewing room (I sure didn't know they had wire thread?), wound this
around the metal contact and the stub of the broken plastic part and then JB
Welded over the whole mess. Seems to have worked. This JB Weld stuff has a
million uses!
Thanks for the overheating advice,
