Hi Paul, What are you using to check your RPMs? Remember that your Distributor turns at 1/2 speed to the crankshaft. So if your dist is turning 500 rpm your engine is turning 1,000rpm. I don't have your specs but most factory weights start to open before 1,000 rpm. Also every dist. that I ever worked on had the same spring setup like yours. The light one works first and the heavy springs comes in at a higher speed. You would get a much better reading if you test your Dist . while it is in the engine. Get a good tachometer and a zero back timing light. and a hand operated vacuum pump. That way you can check your vacuum advance too. If you want I will help you do this testing if you get the tools to do it.
