I'm trying to rebuild a Stromberg 150 cd carb. I think it's a CD4T (original
carb on engine FM130466 UCE).
1) I can't get the needle out of the air valve. I took out the grub screw on
the side. I can wiggle and spin the needle and pull it out approx. 1/8"
against the spring which pulls it back inside the air valve when I let go. I
am concerned that pulling much harder on the needle might screw it up. The
needle seems to sit inside of a sleeve which doesn't budge at all. Shouldn't
the needle and sleeve come out as a unit? I have the carb adjustment tool
(read allen wrench) and have backed the adjustment off many turns
counter-clockwise as the manuals suggest. Where do I go from here?
2) The needle is cruddy (car has been sitting for 15 years). If I can get it
out, should I automatically replace it or is cleaning and reusing it a better
bet? Grose-Jets?
3) How do I go about cleaning out the fixed jet inside the carb body. Is
bathing the dis-assembled carb in a bucket of carb cleaner the only way to
clear this up? Is this jet replaceable?
4) There is a black 1/4" plastic spacer between the carb and the intake
manifold. It has formed a serious attachment to the carb. Is there a trick
for getting this loose or just shred it and get a new one?
Sorry for the length of this but thanks for any help.
