aha, id never done it but i presumed the slotted screw above where the fuel
line comes out could be used to trim individual lines, shows waht i know.
fuel pressure in the system can be adjusted as a whole, but its a bit
drastic, if all else fails and you cant tweak it out on the isle
mixture-screw-thingy on the distributor,if you run out of things to try, on
the radiator side of the engine is the fuel pressure regulator (sorry if
thats not what its called) unbolt that, underneath is a brass cap,
pull/drill/butcher that, and you will gain access to a factory set screw,
winding the screw in richens the mixture as i remember.but dont rely on my
memory, i used this method to set the fuelling on my car when i removed the
gauzes out of the system, which then allowed too much fuel thru.
That little secret was gleaned from somone of the list a while back........
