Stock DeLo is set up for full scale vacuum advance off the manifold. Uses a shut-off solenoid at idle (wired into same circuit as idle speed motor) and vacuum enrichment in CPR when throttle plates open. Because my Renault re-engine lacks both (CPR is coil only), set it up accordingly. Is much simpler and less prone to problems, but do think I'm missing slight performance advantage of enriched fuel mixture (no full throttle switch/Lamda valve either). Oh well -- the cost of reliability. Bill Robertson #5939 >--- In DMCForum@xxxxxxxxxxxxxxx, "cruznmd" <racuti1@xxxx> wrote: > I'll try it both ways if I have to.
