What is the static timing on a Type 65? - I assume less advanced than the 1 3/4" / 20° BTDC quoted for the 4.8:1 compression engines, but I have been unable to find the data for my engine, which is the original 65.
The '36 Ruby (C/R of 6:1) is quoted as 3/4" BTDC at the flywheel, which I reckon to be 8 degrees, so I am inclined to start there in the absence of better info.
I am new to Sevens and to manual timing on the steering wheel. I imagine my best course may well be trial and error, but I'd quite like to know where I should be starting from!
