[Special Coupe Frank]

"Standard" instruction on the GAV is to close it fully, then open 1/2 to 1 full turn for starting from dead-cold, then to close it to 1/4 turn from closed once the engine is warm.

With my unrestored 84,000 engine, in cold weather I find I have to have the GAV open about 2 turns for the first couple miles, then can close it down to about 1/2 turn open.

In the summer, I can run it 1/4 turn open.
