Holley 4000 Carburetor Repair Kit K4005

Thanks for the videos, very helpful. Nice kit for the money. Shall purchase from Mike's again when needing carburetor parts.

Kit and diaphragm worked great

Kit has all you need for rebuild. Thank you

Everything seems to fit well and appropriate. Material quality is very good. May be a good idea to create a parts listing with numbers relating to all photos and sketches - both disassembly and assembly.

Excellently put together and great support. Very helpful

The kit quality is great but I did not use the new screw-in fuel inlet seat. I cleaned the old seat and used the new needle. I recommend trying to source the old style seat. I know cores for the 4000 series are becoming rare but sometimes parts are missing and it would be nice to be able to get used ones(parts). My carb was missing the retainer bracket for the secondary fuel tubes. Also, the tech lady could not give me a good answer on how to change the secondary fuel tube O-rings and o-ring retainer washers. The washers are staked-in at the factory. If the kit furnishes new O-rings/retainer washers then there should be clear instructions about how to change them. As I said-the kit quality is great and I would buy from Mikes again!!

was a hard item to find. will always check mikes carburetor for parts. they always have the right item

Very good kit. Car runs great now.

all parts fit as expected great sales team knowledge

The kit had all the parts I needed and fit perfectly!
