Frequently Asked Questions – K1138 Holley 1940 Carburetor Rebuild Kit

1. Which carburetor does the K1138 kit fit?
The K1138 kit is designed exclusively for Holley 1940-series carburetors, popular in older AMC, Ford (including agriculture) Hobart and Jeep vehicles. Please confirm your carb model before ordering. Kits fit the carb number not the application.

2. What components are included in this rebuild kit?
The comprehensive kit includes:

Viton-tipped needle & seat
Accelerator pump cup - ethanol resistant
Float bowl gaskets & O-rings
Check balls
Pre-cut gaskets and seals
Power jet

It's everything needed to refurbish the fuel and accelerator pump circuits in a 1940 carb.

3. Is the kit compatible with ethanol-blended fuels?
Yes—this kit uses Viton and modern gasket materials that resist degradation from E10/E15 fuels commonly used today.

4. Does the kit come with a float?
No, the float is not included. The Holley 1940 cartridge-style float must be purchased separately.

5. Are installation instructions provided?
Absolutely. A free electronic rebuild manual is featured on the product page, offering step-by-step guidance and tuning specifications.

6. How can I verify this kit fits my carburetor?
Check for the "1940" carb number on your Holley carburetor. If your carb number is stamped as 1940, this kit is a direct fit as long as you match the carb number r-xxxx

7. What performance improvements will this kit provide?
An updated accelerator pump cup, fresh needle/seat, and new seals all help restore crisp throttle response, consistent acceleration, and eliminate fuel leaks or idle issues.

8. Is this product available now?
Yes. The K1138 kit is usually listed as In Stock under the price. Inventory status is updated in real time.

11. How does the K1138 kit compare to others on the market?
This is a Made-in-the-USA kit with high-quality Viton and ethanol-resistant parts—far superior to generic or NOS kits that may degrade with today’s fuel blends.

Great kit. Solved all my carb problems. The 1940 carb was easier to rebuild than I expected. Great videos by this company on their site and youtube to help.

Mechanic

Carburetor off Ford Industrial powering a wood chipper. Had heavy internal corrosion and clogged passages. I needed to glass bead the float bowl. Idle tube is not removable - cleaned with #56 drill bit and lots of compressed air and carb cleaner. Mike's parts were all excellent and the kit plus the optional kit contained everything I needed. Mike's manuals/videos were quite helpful. Saved this carburetor and saved me lots of money.

Carb kit

The kits are great and the instructions available on the website are great for disassembly. These carbs were used on many different applications and parts were changed over the years so you need to pay careful attention to the old part you take off and compare to the new ones in the kit, especially the gaskets. Only suggestion is to supply instructions of how to reassemble rather than just saying reassembly is reverse of disassembly.

My age is showing. This is an oddball carburetor anymore. I was concerned I'd even be able to find a kit for it. Found it easily on Mike's website and priced well besides, so I ordered it right away. I was kept informed of the order status. The kit arrived promptly and a visual review confirmed it was exactly what I needed. I'm pleased with the entire experience. Thanks for the chance to comment!

Good Source

The kit showed up really quickly, everything that I needed was there, now my '67 Ford is running like it should, thanks for being such a good source for what is becoming a hard to find item. I really appreciated the information that you have on your website as this wasn't a factory carb and if it ever had a tag, someone had removed it, without the accurate information with pictures I would have had a difficult time finding out what kind of carb it was and getting the right kit.
