Help with idle - holley 4150 -

Replacing Holley 600 with 650 holley transfer slot adjustment If I remember right you don't want more than 060 of the transfer slot showing, I usually set the secondary throttle blades open to that point slot depo ovo I just read in an old Holley manual that the transfer slot circuit can be tested by Slowly opening the throttle with the idle speed

4 slot pot cores About inch from the carb's underside should be regarded as an absolute limit Excess transition slot usage also causes the idle mixture
