As time goes by , more and more of you will begin to tune by feel and sound. So here are some notes. We were asked : What are the signs of advancing timing too far? Shawn Wright The Hillbilly tuning procedure makes it clear that you should move the pump a pencil line at the time. If you do it that way , you have nothing to fear. When it gets too far the noise in idle ---( the marbles on the plate get bigger) gets louder. From where you can detect it and to the point where it will hurt the engine ---is many pencils. Do not do a Hillbilly and then do the injectors. The sequence is important, first the injectors then the Billy. Now for the rest of indications lets ask the mechanics here ---how's about it Loren and Ferguson ?. Mine starts "too good" and no smoke on a cold startup. Does it wind up as overheating ? maybe.And very rough idle.?. Hagar.
