I see thank you.


I ordered the plate and springs, and they ain't cheap anymore! $69..

I've taken apart the WPO distributor. The slot plate that came with it doesn't even fit over the weights properly, and there are some hefty springs on the weights. I don't think the sloted plate was even stopping the weights.

If you are talking abou the FBO plate, yes they often stop the advance before the long looped, heavy spring is engaged. That's why its generally better to weld up the inside of the slots. Points distributor for drag racing this isn't as important. But for any electronic distributor and for almost every other use, engaging the heavy spring is better.

Here's how and why is pretty well illustrated with Rockable (360 Tune Up) and further discussed with Mullinax.
