Thermoquad issue

@Bewy knows his stuff, so if your junk is working, don't mess with it.

38*seems like a lot for street; if you can make it work more power to ya; but it is telling you something about the efficiency of your combustion chambers.

For reference;
with the transfers shut off;
where are your mixture screws set?
and do you happen to know what you set the float height at?
and if you have a fuel-pressure regulator; what have you got it set at?
Do you know your cylinder pressure or your compression ratio?
And finally, do you know what your cam specs are, or what cam is in the engine?
I just want to know what works for future story-telling.
