1979 Carb Rebuild (Pt 1)

I just received a complete set of carbs from a '79 and thought some pictures and explanations of the complete tear-down and re-build may be of help to others. The pictures are self-explanatory. Part 2 of the tear-down to follow.

More tear-down pictures:

Hi Scotch
How do you remove the pilot air screws. I have a set where the previous owner has obviously burred the screw slots by not using the correct screwdriver. I am a bit stumped on this and am thinking that I would have to drill them out as a last resort.
Any ideas
Cheers
Rob

The tear-down continues: Some pictures may be out of apparent order !

If the idle screws are buggered then you're going to have to try to screw them back down, drill them and use an extractor. The very thought sends chills up my spine!

Re: Pictures 3827 and 3828 - What you see in the venturi is the stream of lacquer-thinner!

NOTE: The seals on the throttle shaft ends could be damaged if soaked excessively in strong cleaners such as lacquer-thinner. The use of lacquer-thinner for manual surface cleaning and gallery flushing using a syringe is OK.
