you said timing is dead on TDC. do you mean its not advanced at all? should be around 10 degress advanced, depends on your combo though. and that's with the vacuum advance disconnected and plugged. the initial timing will be more with the vacuum advance connected(if you use manifold vacuum). i know there's a lot of debate on the ported vs. manifold vacuum, but i agree with manifold vacuum all the way. i have the same carb and i think you said you had hooked the vac advance up to the driver's side port. i believe that's the manifold vacuum port, which is what i use. i noticed a difference in performance when i switched from ported to manifold.
and there's a pretty slim chance you got trash in the new carb, but it's possible. i've cleaned crud from the needle and seat twice, makes the engine idle horribly. i'd mess with the idle mixture screws first though, see how it affects it. also, the tuning kit is a great idea, i bought one. but the metering rods, etc shouldn't affect your idle, that's controlled by the idle system. good luck [img]graemlins/thumbsup.gif[/img]
