[AT] Questionable ignition coil

[Cecil Bearden]

I bought 2 of them about 25 years ago from OSU  Technology at Okmulgee.  
The vacuum pump is the wear item and I just use a hand held vacuum 
pump.  I modified a bracket to drive a magneto on the lathe.  The 
distributor machine does not have the torque to drive the impulse.

I usually take the distributor out to install points and set them on the Sun Machine.  Probably 9 times out of 10, I end up rebuilding the distributor.  I quit buying rebuilt distributors, they are just crap....  With Industrial engines, there are not many rebuilders around...  This is where my lather and mill pay off big time..

Our 1949 AC G would not start a few days ago after being parked for a short period of time. A quick observation determined the contact points were beyond use. I went to the local auto parts store and was advised I probably should replace both the points and of the condenser because they felt like that condenser went first and it caused the points to burn up. With this information I also purchased a new coil even though I wondered if the coil was a bad.
