Distributor curve help needed

Ricks70Duster340 said

I found a heavy long looped spring in my stash, so replaced the black spring with that. Also replaced the gold spring with the lightest which is silver. That change produced:

500-18*
1000-18*
1500-20*
2000-25*
2500-25*
3000-27*
3500-27*

Lets see what you got.


Still holding the weights back at 1000 rpm.

Might be better yet if you have a Chrysler light spring in your stash.
Softer spring rate will have thinner wire and/or more coils.

With the existing two springs, on the silver spring increase the loop or slightly bend in the sping perch.
It's the spring tension that is keeping the weight from moving outward with acceleration.
The tension is a combination of the distance the spring is stretched and the spring rate.



Reducing the tension on the primary spring will let the weights move out at lower rpm.
Advance curve will start earlier


Then to delay the heavy spring, bend the long loop perch slightly in.
