I agree completely but it does the opposite at operating temp. The cold idle just after it runs for a couple minutes before hitting 180 and all other throttle positions are just fine. My next move is to set the timing at 24 initial, see how that goes. Then, try a different combination of advance springs and see how that works or not. I'll put the chrome box back on too as I have ruled that out as the culprit.

After that I'll wave the white flag and deal with it as is.
