Tuning For Detonation

Instead of guessing on these 'Dizzy', find an old shop that has a Sun Dizzy machine and run it in.

Its like Guess 20 times or Spend $50 and know. I found a shop that had one. He showed me how to use it and allowed me to set the advances, go test it on the car and come back and tweek it for $50. I used one in Community Collage so I had the basics already. This was before the FBO plates so I was welding the slots and grinding. Changed many springs and a few advance cans too.
