Re: Northeast distributor advance spring

The two springs in the 740 distributor are different. If you cannot find a correct spring I will strip mine and measure the spring so you can have one made.
I recently had a problem with my 740 that is relevant to this question. The car was running normally and suddenly stopped as if the ignition had been switched off. It then failed to start after many attempts over a period of time with no sign of it ever firing. After checking all of the basics I discovered that one of the springs in the distributor had come off and had been mangled by the weight. I doubted that this would have stopped it from firing because although it would have over advanced the spark for starting I had been manually retarding the spark which I thought would compensate.
However, it had to be fixed and my local source for springs did not have a standard one that was close but to my surprise they said they would make one. They measured the wire diameter, number of turns and the distance between the pegs in the distributor then made the length so that it had a little tension. It may not be identical to the original but it would be close.
After installing it in the car it started after a fair bit of cranking and after clearing the excess fuel from all of the previous start attempts, it settled down and ran normally.
