[TR] Diaphragm material

[Michael Lang]

I am toying with the idea of replacing the diaphragm in my vacuum
advance rather than coughing up the money for a complete new one. Why?
Pick one:
1) I am cheap
2) I have too much time on my hands
3) Just to be able to say that I did it.

All three are probably true to some extent. Anyway, does anyone have a
good suggestion for a source of material that would work well as a
diaphragm. It would need to be some sort of rubberized fabric that is
fuel and oil proof.

Feel free to tell me that I am nuts. :-)

Thanks,

Mike
