1950 H Commodore Acceleration Question

[JFromm]

I have a 1950 Commodore 6 and lately, when I am accelerating between 34 and 42, the car starts to ‘break-up’; once I pass 42 drives fine. If I decelerate to 32 and then accelerate over 42, the car drives just fine. Any ideas what is going on? Thank you!

Take a close look at the points and the wires within the distributor. Make sure the point rubbing block is intack and assuring the correct dwell. Check the point clearance on several lobes. Check the wiring inside the distributor that should be insulated is indeed insulated. Also check the wires to and from the coil to make sure they are clean and tight.

Good Luck

I'm no expert, but I seem to recall that if you put a timing light on the flywheel and watch the TDC mark, then gradually accelerate the engine, there should be a smooth movement (advance?). If it is choppy, that means there may be a problem with either the vacuum advance or the centrifugal advance in the distributor. Anyway, that would be one way to remove the distributor advance as a possible culprit.

I had a similar thing with my Hornadore. Point wire was rubbing the breaker plate when it rotated, thus shorting the motor.
