adjusting q/jet choke pull off ?

(1/1)

bober:
Just how much vacuum do you have to have on the pump meter to adjust this properly ? Thanks

Frank400:
at least as much as you have at fast idle.  I always check at 20 inches of vacuum.  i never tried but I think it pulls in completely with much less than that.

bober:
Can someone run that by me again on the procedure for setting the choke after the vacuum is applied ? Thanks

FOUR inches of vacuum has completely seated this Q-jet choke pulloff.
