I jetted my carbs as per some recommendations from a fellow member on here,
2.0 pinto some head work and twin 40 dcoe carbs.
had it on the rolling road the other day, I knew it was rich at idle befor I went as it was black smoking at idle.
the idle screw isn't even 1/2 a turn out and it's showing about 10.5:1 on the air to fuel ratio
at full throttle it goes off the scale rich and won't even pull through, the only way to get a run was part throttle until 2500 osh then full.
i know I need smaller idle jets and I understand that f8 a leaner jet than f9
i currently have 55f8 idle and I think I have in my toolbox a set of 45f8 that I might try.
my question is, is there a rule of thumb or a calculation to work out what would be best or is it a case of trial and error?
also I have f11 tubes with a 135 main and 180 air corrector but it's running off lean between 3500 and 4500 to about 13.7:1 and then goes to 14.3 upto 5500 where we stopped as its lean.
i think I need a bigger main and a slightly smaller air corrector, is this correct?
the rolling road graph of only part throttle until 2500ish
