There is a Dellorto tuning book available through either The Real Source or California Imports, i can't remember which. It is a good book,though, check them out.

there is only 2 adjustments
Idle speed and mixture.
Set you idles (with a sync tool) with linkage disconnected and then adjust with mixtures.
In for lean
Out to richen
Repeat as necessary till idle is right and mixture is "best lean"
If you have an electric fuel pump you WILL need a pressure regulator.
Do not go over 3 1/2 lbs pressure - and a will be guessing you are way over

thanks, I got the same result when I touched them about a half day but didn't get to know whitch way its leaner. U r sure that I should turn the screws in when its smoking black? Then it really needs a regulator because it didnt help a lot......could you show me some excample to what I should look for?
How can I be sure that the problem is with the pressure and the jets are not too big?
thanks alot (my first experience with carbs)
edit: Is it possible that too high pressure is the problem for leaking when I turn it off? there was 0,3 bar written to the box.....a bit under 5 psi would act like that? (4,3lb)
