Car is a standard Triumph Dolomite Sprint, normally with 2 13/4" SU carbs, i had changed it to 2 40DCOE 18 (9E+9F) webers, using TriumhpTune set up.
choke 32
aux.vent 4.5
main145
emulsion tube F16
airjet155
idle jet 50F9
pump jet 40
bleed back 0
no airhorn
Now i wil ask, the car is used as a daily car so economy would interest me a little, i have a set of aux venturi 3.5 and a set of 30 chokes what would happen if i change venturi or chokes or both of them, i think of mileage pr. liter.
Question

i dont know what the aux venturi will do. but the main choke tube, smaller will give more low end torque, and maybe less top end. you can run smaller main jets with the smaller choke tube for more economy. You can play with the pump system as well,
