Rotor Height
Hi all. I had a question about the distributor rotor and could not find information anywhere else. It looks like my rotor is sitting too low and will not make contact with the spark plugs. I am getting spark at the points and the rotor spins when turning over. Is there any way to adjust this, or does the rotor contact normally sit lower than the spark plug points?
Thanks |

Re: Rotor Height
No. The rotor should not be sitting lower than the points. Hard for me to think about how this could happen. Did you remove the cam? In this forum there are pictures on correct location of the rotor when the Model A is properly timed. Do you have the Les Andrews "RED BOOK"? There are many illustrations in there as well as much infomration on how to service your A.. Send me an EMAIL and I can send more info to you. Also be sure to join a local Model A club.

Re: Rotor Height
Cam has not been removed since I have owned it. Thanks for the advice. Found out last week that there is a local club in the next county over.

Re: Rotor Height
You do not want the rotor to actually touch the contacts on the inside of the distributor body. There needs to be a gap. This thread should help.

Re: Rotor Height
Missing the lock washer under the large flathead screw that holds the cam in place?

Re: Rotor Height
I had a similar problem but my rotor was to high. I had a new distributor body that was to low and caused a premature rotor failure . I suggest you get a origin Ford body and measure and compare the two. Some of these replacement parts are not up to Ford spec.
