I have twin 40s but they are jetted for a 1.8 ford.
There is a list here for the different jets, do I need to get all of them? i.e. will the choke jets etc be used on track driving or can some be let as they are?
1400cc
Choke size: 27mm
Main Jets: 110
Emulsion Tubes: F11/F15/F9/F16
Air Correctors: 160
Idle Jets: 40/F9
Pump Jets: 30/35
Auxiliary Venturis: 4.0
Just trying to see if I can cut any costs as buying all the jets seems to be quite expensive.
Also, I have no trumpets, does this cause running problems? Can I attempt to make trumpets (not worried about how they look)?
Thanks
