I cleaned a little and adjusted the floats, then reassembled. I noticed a bit of improvement in both acceleration and stalling behaviour (placebo effect maybe) so I decided to move on and rebuild the whole feelthy mess.

To familiarize myself with all the parts, I spent some time reviewing exploded parts diagrams and pics I found online. I made up a clean place to work with a lot of space to keep all the parts in order. I took a shi†load of pics during disassembly for future reference. I decided to use lacquer thinner to clean the parts so I bought a gallon along with a few aluminum baking pans to wash the parts in.

The disassembly was straightforward and required only a basic torx set, screwdrivers, and something to handle the tiny spring clip retainers. I did the air horn first; disassemble, clean, and reassemble. The screen at the farthest bowl inlet had captured a lot of particulate matter.

Then I did the main body. Doing it one section at a time like this kept the number of loose parts more manageable. I found a lot of debris in the bottom of the bowls. Once dry, I brushed out a large part of Utah (sandy particles, see pic below). The pump check ball was stuck in the bore but came out with a few taps on the bottom of the carb (hmm).

As I removed the parts, I placed them on my table in their relative positions so I would’t go crazy trying to put it back together later. I used two cleaning baths, one to wash most of the crud off, and another, cleaner one for a second cleaning and then blowing out of the internal passages. I used a toothbrush and a set of small tube brushes to clean in around and through. I washed out an awful lot of dark brown stuff.

I saw your post in my 9906 refurb edelbrock thread and came here like you suggested.

How much $ did you spend on parts to do the rebuild?

Thanks,
Robert

I bought Edelbrock rebuild kit and floats, plus lacquer thinner and other incidentals, about $80-90. There are cheaper kits out there (eBay) but I stuck with Edelbrock because I hadn't done one before.

There is a lot of external stuff that Edelbrocks need, fuel filter, fuel pressure regulator, fuel gauge, fittings and so on that could run you another $100+ easy if you don't have them.

All this stuff is itemized in my list. Some guys don't want to deal with all this and just go buy one complete. That works, too.

Thanks,

That's close to the numbers I was getting.

I already have the Holley Regulator and Pressure Gauge.

I'm thinking I'll just get the 9906 (refurb 1406) this time around.

Thanks again.

NP, I'm gonna read through your Service Truck Build thread, looks interesting. I was seriously considering a 1967 plumber's truck while I was looking for mine so I can see what I'm missing by reading yours.

Jim,

Thanks for the link to your fix for the trans leak at the speedo gear. $2 worth of seals from the local tranny shop and no more leaks.

Good deal, Dave. I'd have to say that little fix did the most for the least amount of money and effort of everything I've done so far.
