How hard is it to rebuild a Holley Carb. if you never done one before?

Go get a book Its very easy

VERY simple! And a book or online help is good use.

My first carb was a Q-jet, but two years later the carb is still running excellently today - on the first engine I rebuilt http://www.nastyz28.com/ubb/wink.gif

Just take your time.
Keep all the parts seperate and put them into some sort of container so you don't lose one.
You can never have too much carb cleaner.
Don't overtighten anything putting it back together.
Get a book.

I've got a set of instructions I bought off evilbay that are really simple and succinct. Let me know if you would be interested and I'll try to scan them or fax them to you or something. Or, you could just buy them like I did ($5).

I like a good book that tells more than simple re-build but also how to fine tune and modify for your specific application

if you get the holley trick kit, it comes with step by step instructions and diagrams. I just did mine back in the fall. still have to fiddle with the float level.

I built my carb for my last motor and just dropped it on this one i havent turned a screw since it was set up for the last engine probrobly runs good enough that most people wouldn't consider changing a thing, i would like to have it tuned on a dyno though, but for the most part once you rebuild it you shouldn't need to touch it for a long time unless you have drastic weather changes, u need to keep a good air and fuel filter on there and she'll be maintenance free

Besides a re-build... the kick down doesn't work. Whenever I step on the gas it just sometimes hesitates and then get going. Before I had the engine replaced it hadd a quadrajet Edelbrock. The mechanic reccommended the Holley but then they never hooked it up right. The transmission place said I needed some sort of kit to make the kick down work. I will post the carb model and maybe some specs soon so you guy can see what I'm dealing with.

Thanks for the suggestions. For a novice how long do you think a re-build will take?

holley carburators are the easiest carbs to rebuild you really don't need instructions.just pull it apart into 6 pieces if it's a double pumper or 5 pieces if it's a vac secondary.then just clean each individual section and re-gasket it,again very very simple.i rebuilt my first holley an old 850dp in 30 minutes even after cleaning it and blowing compressed air thru the passages.

About the hardest part of rebuilding a holley carb (vacuum sec.) is putting that damn sec. diaphram back in right so it doesnt leak. Other than that they are by far the easiest carbs to rebuild, most two barrels are harder than the most complex holley 4 brl to rebuild.

The only other carb that is any easier would be an edelbrock performer carb, they really only have to major parts.

I rebuilt my first carb about 6 months ago. It was a Holley Qjet, SIMPLE. I had crappy instructions with me so I basically just figured it all out myself. Just yank it all apart, dip all the parts in a pal of carb cleaner, and throw it back together. You cant mess up unless you lose something. Only thing with mine is I dont have the choke working. Doesnt matter though, dont need it here. Get better rods and or jets while you've got it open too.
