Single weber dcoe xflow
So I know every car is different and I will get it rolling tuned but...
Is there a starting point of which jets I should use??
Single weber 40 dcoe
1600 xflow
234 cam
Ported and flowed head.
The jets in there are way over fuelling.
The throttle position screw has the be fully wound out.
The mixture screws do not bring it down enough.
Any similar setups?
Currently I have 60f2 idle jet, 145 main jet, Emulsion tube says f2 and 180 air corrector jet.
In a spare carb I have 45f9 idles, 120 mains, f11 emulsion and the same 180 air correction jets.
I'm guessing the 45f9's are more suitable but the others? Or what else should I get?

Re: Single weber dcoe xflow
If the carb has air-bypass screws make sure these are all wound in.
Check for air leaks on inletmanifold and/or throttle shaft and check throttle is not bent.
Then only change idlejet to 50F8 or 50F9 if it is an older Italian Weber or change to 50F6 if it's a newer (Spanish) version.
Leave 145 main jet, F2 tubes and 180 air jet in but check that the jets haven't been bored out.
