This is the second rebuild kit I've gotten from mikes. A 1904 Holley on a 55 international. It's the video's that render this man's work as invaluable. Clear, concise and with bit's of "oh, by the way" I don't need to use the rebuild kit now. The previous work is holding fine. I'm stocking up the inventory for this 60 year old machine. As a matter of fact, I also got the glass float cover. Yeah, he had that. If your doing any kind of a build, make sure Mike is on your vendor list. He is Fast, Fair and almost Funny in the videos. Almost. Jon Forsman - 55 IHC R-110

Not only was the kit everything I needed, It also got here in the 2 days as advertised. Truck is up and running with very little tweaking. Follow along with the online videos and its really quite simple. Price is great, and tutorials are also. Thanks!

These old Holley's are hard to find parts for. Mikes is a great source with very good info to identify the carb and get the right parts. The kit was thorough and the right one for truck I was working on. My customer was very pleased at the price.

This kit had EVERYTHING required to rebuild my carburetor to very nice working condition ( no more stumble or hard starts ). The kit arrived in perfect condition....ready for installation. My 1963 Scout 4 cylinder fires right up in 8 below temps !

The kit had everything needed to rebuild the carb for my 65 I.H. Scout. The on-line video was particularly helpful and allowed me to do the rebuild step by step without guessing.

Holley 1904 rebuild
Fantastic! Exactly the right kit, after having other retailers recommend the wrong kit. Mike's is tremendous in its knowledge of old Holley's. Other retailers did not even know the right place to look for the carb number. I have a 1956 IHC dumptruck and was having a very difficult time until I came across Mike and his videos and website. Fantastic - thanks for all the help!

This man is all about his customers an is the best at what he does by far! Though my carburetor list number was listed in this kits fitment reference list, the accelerator pump in mine had the long shaft rather than the short one included in this kit. Was surprised that when I called the support number that I actually spoke with the man himself. Super nice guy and very helpful, he had the correct pump in the mail to me right away! Even better was his 4 part Video collection on YouTube for the disassembly and rebuild of this exact carb, it was a great reference and a testament to his dedication to what he does. Old Tank never ran so good. Thanks Mike!
