Re: Thermo-quad Tips
.074/.075 primary (Holley) no metering rods
.143 Sec. with .790 Air door
OR
.137 sec with .750 Air Door
(Stock unmodified Air Door specs.)
3 turns on Air Door spring tension
These are conservative but will be good baseline in my opinion.
Do not modify emulsion tubes!
9800 Series are excellent carbs to start with.....a replacement carb
calibrated better than the factory installed stuff.
