Initial timing how?

For an MSD distributer, set your initial timing at idle. After that chose the correct colored bushing (they come with the distributer) for the amount of total timing you want…..so for example if you have 12° initial and you want 32° total timing then you would want the bushing that gives you 20° advance. How you apply the advance has to do with the different colored springs that come with the kit.

I hope this helps.
