too high compression?

Thanks, new carb. clear float glass right on the money. Only thing I altered was the curb idle speed chasing a sluggish choke but I got that straightened out. Now it starts up with one pump and warms up fine. Will advise on new EGR setting. Does anyone know offhand when the EGR is supposed to open, ie what RPM? 2000-2500? Or does it depend on other factors. It is venturi velocity vacuum operated as the sense line is above the butterflys on the carb, then goes into a vacuum amplifier, then through a thermo valve that seems to not be functional as it should be closed when cold and only open when up to temp. Another out of production part Ill have to source. Who said the chase was more satisfying than the victory?
