Does anyone have an idea where I can find material suitable for making fuel pump and metering diaphragms? I would like to locate some of the Mylar/Teflon material if possible.
Maybe something like these? They have straight up teflon sheet too, but I wouldn't think it would hold up as well to wear and tear like mylar. I have no idea what these are like, was just poking around out of curiosity. McMaster-Carr has a bunch of stuff listed on their site, and even some "make your own" sheet gasket. Might be worth a call to them? Gonna cost ya coming from MC though.

Need ideas on Pro Mac 10 10s with no spark.
Did you check the points/condenser while you were in there? I'd at least give them a good filin' and set them.
Could also try an ignition module. I know some frown on those, but having just worked on my BIL 10-10 with one, I was reminded how well they do at low RPM.
FWIW, I've gotten one of those coils so hot the plastic started to bubble (long story) and it still worked - they're pretty durable.
