I am rebuilding a set od 150CD's right now too. What's the best way to
center them when reassembling.
The method I learned from Smitty is a slight variation on the others.
First screw in the jet and jet locking nuts all the way to the top
until they are flush with the body. Make sure the piston and needle
are not installed when you do this.
Now, loosen the jet locking nut (not the jet) about an inch. Install
the piston, needle, etc....the whole top part of the carb.
Next screw in the jet locking nut about 2 turns then lift the piston
with your finger and with screw driver slap the piston down with some
force, alternately lift and slap the piston down about 3 times for each
adjustment of the nut. Screw in the jet locking nut 2 times and repeat
this process until the locking nut and jet are again flush with the
carb body.
Now back off the jet one and a half turns. Your carb is now centered
and your jetting set for startup (you can reset the jets as needed for
lean or rich, see the book for that procedure).
The piston should fall freely, as Jarrid described, without hangups.
