twin 40's

any one know what air jets etc I need for twin 40's on a 1.8 zetec ?? and how the f do I balance all 4. do they each have a sepersate screw ??? if so where the hellm is it I have manged so far to get an even mixture however the mixture screw is only out about 1/2 a turn at max.

I have a carb balancer which shows two chokes are measuring 6 and two measuring 7 at 1500rpm each carb having a reading of 6 and 7 respectively





Life is like a bowl of fruit, funny how all the weird looking ones are left alone

Are the spindles twisted? there is no separate screw for each butterfly.

There is a separate mixture screw for each cylinder.

Theres a good tuning guide somewhere - I'll have a look and post it if I can find it
