I have been trying to start my 261 just to see if it would fire up. Getting no fire at the plugs or across the points. I noticed there are two ignition condensers, one in the distributor and another on the coil. I've never seen this set up before and am wondering why. The engine was a replacement in a '55 school bus. Casting date on the block is D33 and the pad at the distributor is blank.
