Holley Carb Rebuild

The Holley website has a Marine Carburator rebuild book in books section for sale.

I used laquer thinner to clean my carb (which Holley approves). It seems to dislove the gaskets better than ordinary carb cleaner.

If you have to do any gasket scraping don't use anything metal. It's very easy to damage the metal, or scratch it. Instead, use a grinder and shape a good quality plastic knife into the shape needed to do the job. Or better yet make some scrapers out of plexiglass, they last longer.

Spray your new gaskets with silicone. They won't stick like the originals.

Grind an old common screwdriver to shape for removeal of the clutch heads screws under the back fuel bowl (metering plate)

Use a #65 powervalve,

Know what's wrong with your carburator. Is the choke sticking? Does it have a terrible idle? The secondaries won't kick in? Floods easy? When you disassemble the carburator look for what is causing the problem. Find a ruptured diaphram, or a powervalve that's loose, or has a cracked diaphram, or a gummed up needle and seat. Find the problem. If you can't find it, chances are when you put it back together you'll have the same thing you started with. I sometimes look at parts with a magnafying glass, parts that look good to the naked eye sometimes don't look as good under a magnafying glass. Some of the books also tell you what to look for for certain carburator problems. Good Luck!!!!

It is easy. The "tricks" are:

1) Disassemble everything EXCEPT the throttle plates from the throttle shaft. Pay attention to how it comes apart. Count number of turns to seat idle mixture screws. Note position of fuel bowl floats prior to removing float or needle valve.
2) Thouroughly clean every single part in carb cleaner.
3) Rinse the parts completely and blow out all passages with compressed air.
4) Put it back together exactly how it came apart. Adjust idle mixture screws exactly as they were. Ensure float position is exactly as it was before disassemble.

Most rebuild kits come with exploded views and specs on setting pump lever gaps, etc.
