The basics of Tuning a Lucas Distributor 

I discuss the basics of tuning Lucas distributors.
I go over the basics of springs, both primary and secondary.
The weights and the different types that are found in the Lucas 23, 25, 45, 65 dizzys,
The importance of measuring the advance cam and checking for wear.
The importance of checking the springs and their strength vs old worn ones.
No details on actual curves are provided, just what goes into tuning one.
