Jefe, just finished rebuilding my carbs last night. Seestheday found a great tutorial with pics a while ago. I printed it out and it made quite the handy reference.

The float needle was jammed so sightly in the housing that even with all the WD-40 and a pair of needle nose pliers i had to yank and pull until it finally came out.  

That's bad! be sure you polish those needle seats before sticking anything back in there! You may need new needles, too..

I am currently having trouble getting the air jet out of the puck.  I've tried putting some penetrating oil into the puck, but havent been able to work the air needle loose.  

Do you mean the slides?

If so, have you removed the large screw down inside the piece? Your slide needles should have some play in them actually. The screw is what holds them in.

Can someone tell me the what the point of the slow speed jet is since it is plugged by the rubber stopper?
Also any ideas to get the air needle loose would be greatly appreciated.

 I can't tell you exactly how it works, but I believe there is a small hole that goes into the slow jet tube underneath the plug.
And yes, Shiny, its supposed to be there
