[Roadsters] distributors

[Patti Dwinell]

HUH?? Are you talking about distributors or carburetors?  At the risk of
sounding ignorant, I thought there were just Hitachi and Mitsubishi dizzys. 
My questions are:
Are the weight springs always and forever two different sizes?
Are the springs supposed to pull the weights in?
and....
How important is it to have the thrust washer under the weights?
Thanks!
Patti
By the way....will the new EI dizzys work with a positive ground?
