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.?.
