They are the easiest carb to rebuild. Tools: flat and phillips screw drivers can of good carb cleaner a single edge razor blade for scraping gaskets. Also a few small wrenchs. There is a holley book they sell at book stores if your not confident.The book gives alot of carb tuning tips along with trouble shooting.
Good Luck Bob
The name of the book is: Holley Carburetors and Manifolds.

Hope this helps.

 

I did it on my 4160. It's not that hard of a job, just keep track of what you take off so you can put it back together like it was. I drew lots of diagrams before I took stuff apart, now I've got a digital camera that I'd use instead.

The Haynes manual for Holley carbs is a good reference (Haynes books are sold at every car parts shop), it was worth the $15 during my rebuild. Also, fordmuscle.com has a great article on rebuilding a Holley with lots of detailed pictures on the process, http://66.96.130.106/archives/1999/12/holley/index.shtml

 

It is easy as everybody says. At auto parts stores is a book "HOLLEY carburetors" by SA design and as matter of fact the rebuild section is for a carb just like yours.

 

Be sure to only buy a Holley brand rebuild kit

 

I use a litterbox pan (No litter) to rebuild it in. I just drop too many parts and it is easier to find them in a big deep wall pan.
If you feel force is required, take a break to study the diagram then recheck your process!
Bottle brushes are wonderful. check a restaurant supply to get some good ones.
Don't smoke!
Don't take stuff apart that you have no business trying to take apart.
Keep the parts you took out and replaced separate from the parts that are not to be replaced and the parts that are left from the kit.
Keep the cat out of the shop!
These are just a few things I have learned that are not in the book and are a bit irritating to learn on your own.

I had never rebuilt a Holley & don't really know a lot about carbs. But I rebuilt my 600 last year & it was very easy. Just follow the directions & you'll be fine. Buy a couple cans of carb cleaner & a few tools that I'm sure you have around & you're set. Compressed air is good also.
And as SuperCJ said, buy the Holley kit only.

 

Be sure and not leave any of it laying out to dry at the back corner of the driveway where no one goes. Sometimes wives inexplicably back way out and almost just might run over the whole thing.

Ask me how I know?

I've had good luck with B/G kits.... Many Holley parts, includes new float adjusting locks, float level brass plugs, idle mixture screws that can be adjusted without a screwdriver...

At less than 1/2 price of the Holley kits.

 

As Cruzer mentioned, compressed air is important. Make sure all of the little passageways in the carb are clear. I've had a devil of a time on a couple of them, but always managed to unplug them. All instructions will warn you not to push wires into them, but guess how I got the really difficult ones. A wire brush can be the donor *G*.
