>> Do I have a problem inside my distributor?I cannot turn the distributor breaker cam in my '54 235 to check the automatic advance. Am I trying to turn the wrong thing? I can turn the entire distributor counter-clockwise to check the vac advance.
According to the '54 Shop Manual page 6-18, I should be able to grab the rotor and turn the distributor cam clockwise, then release to check the automatic advance (weights/not vac). If the cam does not return, then the distributor should be removed and repaired.
> Shop Manual 6-18, "Ignition Distributor" step #3>> If I have a problem - can I fix it without removing the distributor?My distributor is #1112403, serial #9D15. The '29-'57 MPC shows #1112403 is for a '55-'57 6-cyl 12-v. A '54 distributor is #1112388.

The engine hasn't sounded "quite right" lately. I haven't noticed any spark ping.
Background:
I started to install new points, condenser, and rotor in my '54 235 yesterday. I first checked the existing timing to serve as a benchmark when I finished installing the points and timed the engine.
According to my
$25 HF timing light, the timing is currently set at 24-deg advance. I posted a Stovebolt question regarding the reading. I am starting this new "Distributor" thread eventhough it may be connected to the 24-deg advance question.
> Stovebolt postToday I started a basic distributor check before I proceed.
