FARM CARBURETORS
FARM CARBURETORS
modern technology for agricultural use
We initially wanted to improve tractor carburetors, but on many the design is so flawed they cannot be modified to work correctly. Technology back in the 1930-1960's didn't allow for proper design so we decided to start over!
Whether you are hauling farm equipment, fire wood, or pulling it competitively, these carbs are the best functioning and most precise carburetors ever designed.
Why not use an original carb?
How do you improve an old tractor carburetor?
Whether you are hauling farm equipment, fire wood, or pulling it competitively, these carbs are the best functioning and most precise carburetors ever designed.
Why not use an original carb?
- Parts support is often lacking for a proper rebuild.
- Factory tractor carbs don't have mid rpm fuel adjustments so tuning is a compromise at best.
- We tested many carburetors from stock to highly modified. NONE OF THEM could pass simple tests for signal variation. Several carbs that were modified by "experts" tested worse than stock!!!
How do you improve an old tractor carburetor?
- The short answer is "You Can't".
- There was no other option... start with a clean sheet of paper using modern science.
- Replacing dozens of carburetors was no easy task but we felt a new American made solution was needed.

We built and tested several styles and sizes of carburetors to match the most tractors possible. Our goal is to eventually cover most applications using three models. The first one is the Farm carb.
"Farm" carb - 250 cfm @ 20.4" H2O - Designed to work on many popular tractors from around 300-450 cubic inches depending on operating rpm.
Threaded base (4 holes) use the common 2.69" center to center distance
1.75" throat inside diameter at mounting base
2.5" outside diameter at the entry (accepts 2.5" i.d. intake tube)
6.5" over all length
Mechanical features:

Mechanical features:
- Low, Mid, and High rpm fuel and air bleed circuits
- Mechanical Accelerator Pump
- Externally adjustable float (fuel level)
- Thread in precision jets
- Four mounting holes allow more fitment options
- Throttle shaft can accept a variety of clamp on levers
This carburetor is intended to replace Carter, Zenith, Farmall Marvel Schebler, and others. Since there were dozens of models over the years, it is not practical to replace or copy every model.
