I checked the timing and it was at 2deg. I set it at about 5 or 6. I dont have an advancing timing light. The manual call for you to install a tach along with the timing light. I didn't hook up the tach. Does this mater??? With the timing at 2, and it should be at 3, what will happen with it being at 2? I drove it and no knock. When would there be a knock? From stop, going up hill etc?
