Re: Minnesota Daily Driver

I'll post some pics later.

The parts I used for the dizzy were new bushings for the weights and the crane cams adjustable vacuum kit.

As far as setting it up, I made my own plate to limit the advance to 10* (stock is 20*) on the advance side. The kit comes with a plate to adjust it on the return side which requires resetting the base timing with an adjustment of the limit point. I set the timing can 9 turns out from being turned fully clockwise. Then I installed one medium and one heavy spring from the kit.

Also if your going to do this I recommend to pull the dizzy and clean/ lube it as well as replacing the electronics while its out. This will help to make sure that you get consistent results.
