That's the part that is making me scratch my head. I don't know if it is possible the carburetor was put together incorrectly and losing vacuum at that point?
I at least now have an idea of where to start and can adjust timing and idle speed to see if that changes my ported side. It may be next week before I get to it, but I'll post an update of my findings.
Another question; Is it possible my carb is too small for my application? It is 600 CFM, but would that affect the amount of throttle plate opening for a given idle speed?
