This past Monday I decided to check the timing on my 1914 and I discovered that the nut was loose on the dizzy and it was able to turn. I set it to 30 degrees BTDC @ about 3000 rpm which gives 8-10 degrees at idle. It was on the car when I bought it and I think it is a Pertronix Flamethrower because it is the big unit with the round screw on rotor. Mechanical advance only. It started to rain and continued for the next 2 days so I didn't get to drive the car until Christmas day-50 degrees and sunny. What a difference- the problems that I attributed to the Weber IDF 40s pretty much disappeared-backfiring and chattering sometimes upon acceleration. I should have followed Al's advice more carefully-he said to always check the basics. Today I did over 100 miles on back roads that we used to race motorcycles on and it was a pleasure-downshifting and accelerating smoothly. I even got a little better gas mileage-23mpg-I was pushing it though.
Happy holidays and New Years to all the SOC family.
