Distributor Help
I need the boards help. I think I finally figured out why my car runs poorly at high RPM. I checked the timing, it is set ok but has ~2 degrees of advance/retard movement at high RPM. I checked the dwell...set at exactly 39 at idle, however, drops about 8 degrees as I increase engine RPM. I increased the dwell to 42 and the car would rev up better but still felt missing/hesitation above 5500 RPM. I checked shaft play and I think that is the problem as there is visible movement at the shaft. I unfortunately have the original Marelli distributor.
Do I need to shell out $800 for a new Bosch unit to replace the aging Marelli? Anyone have leads for best price?
If possible, what used Bosch units can I purchase and refurbish?
What do you recommend?
Money is an issue but don't want to save on a used distributor to end up having it cost more by the time it is refurbished.
