Here is my setup:
idle 65
idle holder 110
Emulsion tube F7
3rd transition hole drilled
Main 140
Main air correction 120
Venturis 40 mm
As you can see my setup is way leaner than yours - still no flat spots. |
From what I could see, you setup is not leaner than mine.
idle 65
holder 110
In my setup I am running
65 idle
135 holder
with 42 chokes - my setup seems leaner
I am still leanering about this but correct me if I am wrong
you are running
F7 tube - which is a richer tube than the F-11 & F-16
Your 120 air corrector w/ 140 main
Mine 210 air corrector w/ 180 main
The air corrector is only used at 4000 rpm and above and even than yours is running richer.
Help me understand if I am understanding this correctly or if I am wrong.
