Guys,
In the near future I am putting a Worked head (L28 valves, decked, ported WRC cam) onto my L20B. It will be fed by a single 45mm weber. I could not help but notice that you are running 34Degree timing!!! Is this apposed to the normal 8 or 10 degrees that a stock L20 with electronic ign runs?????????????????????????????
