Re: [DML] Tuning Idle Speed Circuit. (was: Re: idle problem)



The vacuum enrichment on the DeLorean's CPR is only active under warm-up conditions, at which time the distributor vacuum is disconnected. As the CPR vac is removed, it is placed on the distributor (so to speak).

I just read carefully the note you attached. The delay valve is in fact in a reversed condition than that called for in the D when used in a spark delay setup because the spark advance needs slowed down some to eliminate "ping". The "Carb" side in that case is attached to venturi vacuum which increases with throttle. The D setup is attached to manifold vacuum that decreases with throttle. The delay effect in the D is a bleed-down where the spark setup calls for a delay in applied vacuum.
