Tick-over adjustment

Post by mickeytwonames »

What is the optimum tick-over speed to adjust a 948 Gold Seal engine to - and how is this achieved without any specialist equipment? Many thanks for any advice? Also, what does the screw with the spring over it do on an SU carb?

Just fast enough that the charge light doesn't come on.
The screw with a spring is the fast idle adjustment for when the choke is in use.

Usually the red (no)charge light WILL be on at idle if you have a dynamo. As slow as possible is the answer - without the engine stalling when you depress the clutch.
