Bob,Check the size of the main circuit air bleeds, they should be .028". ....If they are larger, it will lean the carb. ........Also,you havn't said much about the engine....The relativly low octane fuel you are using brings up the question of the engine being over carburated...........If the engine /cam head combination does not produce enough air flow at the booster,the resulting poor signal will not pull adaquate fuel thru the booster. .....I've usually found this to be the case when jetting changes are 3-5 jet sizes above stock,and the car still shows lean. ..........Tom
