1987 318 Tuning with Summit Carb

Compression is good enough. 1 - 143, 2 - 147, 3 - 130, 4 - 137, 5 - 140, 6 - 135, 7 - 150, 8 - 142. I daily drove this thing in FL just up to a year ago and never had an issue. Plugs are caked in carbon, go figure. Wires, cap, rotor all seem fine and are less then 2 years old. Dizzy shaft feels fine.

I don't know why I took off fine and after 5 minutes it started backfiring as I was driving down the road.
