Hi All,
I have a desmogged 1974 fj40 with original Aisin carb and a DUI distributor. I am struggling to get my idle set right and am going back over everything...I have the DUI manual but it is not specific. WHen I had this distributor running my motor before, the motor was smogged and with that black box emissions thing, I am not sure if the source was manifold or carb-ported above the throttleplate..
Can someone please confirm it DUI distributors with vacuum wants manifold vacuum or ported vacuum?
Also, do you guys lock the distributor timing and disconnect the vacuum advance on the distributor when tuning the carb idle mix and plate position?
Thanks!
