I replaced the thermostat with new Stant heavy duty 160 degree. Seems to do
much better. I think the old one was letting too much water through.
Other Item: I reset timing to about 18 BTDC. It was a little higher and
had slight ping on load. I am burning 92 octane. Is 18 degrees still too
much? Any more retard seems to contribute to overheating.
Other Item: Running the Weber downdraught and the engine idles with idle
screw backed full out and idle jet full in. Where is it getting it's air?
Sounds like a problem, but I don't know where to start looking.
