Vette(s): SOLD - "The Toy" - 1970 Convertible SOLD - "The Beast" - 1990 ZR-1 (#682) "BLKBRRD" - 1978 Trans Am, 400ci/285hp, 4 spd, Black w/black interior, Hurst t-tops
In the spring of 2000 when I bought "The Toy" it came with a Holley 650 CFM spread bore 4 barrel carb. I know it isn't original to the car but it has worked well until recently. The secondaries have been sticking and won't close completey causing a high idle speed and the fuel mileage to tank. So I figured a rebuild was in order. Got the correct Holley rebuild kit and will be trying the rebuild myself over the next few evenings.
25 years ago I watched my brother-in-law do a rebuild of the Holley 850 Double Pumper that was on his '70 AMX and I assisted (basically watched) a friend in the rebuild of "BIGBRRD's Q-Jet. I've already been warned to take things apart carefully as springs and parts can go rocketing off into the far corners of the garage.
Any other tips for a novice?

Those are two words that just don't fit together: Norsky & novice. Now I KNOW for sure that there is absolutely no hope for me
the best advice has already been given.....clean sheet (steel balls and springs do not roll as well on a sheet compared to a hard surface) and use BRIGHT lights (you might have to take off those Norwegian Flag sunglasses.....you can always send those to me hehehe)
Breast (OOPS...my bad ) I mean BEST of luck to you!

Lars on the Corvette Forum has lots of literature on rebuilding carbs and distributors. If you contact him, he will email fresh copies to you for free. My Holley Spread Bore just came off yesterday so I'll be rebuilding too. One of the things I learned from Lars papers is to set the secondary throttle plates to uncover the idle transfer slot by about .020. I'm hoping this will correct a big hesitation on mine when the secondaries began to open.
