Default Re: Spark Plug Condition

Experiment with the GAV. While the engine is running, turn it clockwise until it stops, thats full lean, then open just enough for smooth idle, for most engines 1/4 turn. When cruising down the highway, I usually lean the engine out, to maybe an eighth turn, then when slowing down open it back to a quarter, or even a bit more. Driving a model A takes both hands, both feet, ears, and brain. If your new to an A, you really should get a copy of the original owners manual and read it well. It will dispell a lot of the bad advice that you will undoubtedly get.
