Not Ranked

I will increase my idle jet to 65 and adjust my holders from 135 to 120 then to 110 and soforth.

I have determined that 135 holder is too lean and the 95 holder is too rich.
I will monitor this from idle to 3000.
Then I will begin to use the F11 E tube with a 170 main and 210 corrector.

I will monitor this range from 3000 - 6000

Anything running leaning from 3000 - 4000 I will increase the main jet
Anything running runnning lean from 4000 -up I will decrease the air corrector

I have read that E-Tubes should not be changed unless tuning on a Dyno. It stated that there is very little change when changing the tubes.

If I need more fuel in the midrange I will then move from a F11 Tube to a F16.

If more fuel is needed for progression /normal driving then I will then use a F7 tube.

It seems like the F7 tube is the richest of all in ralation to the F11 and F16.

Does this sound correct?
