FARM CARBURETORS
FARM CARBURETORS
modern technology for agricultural use
For us it began as a simple task. Modify 1930-1960's style agricultural carbs so they work better than stock. 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?
Where do we make them?
Right here in Wisconsin! We support American workers and suppliers so we will never make them overseas. Straightline Machine handles the bulk of machining while various American companies provide material and parts. We perform the rest of the parts manufacturing and final assembly here at C5 Performance.
Why not use an original carb?
- Finding a rebuildable core is difficult or impossible to find (70 year old parts).
- 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 without compromise".
- There was no other option... start with a clean sheet of paper using modern flow data to build a carb that delivers steady air-fuel ratios at all rpm and engine loads.
- Replacing dozens of carburetors was no easy task but we felt a new American made solution was needed. Future accessories might include base adapters, air filters, and electronic controls.

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 @ 20.8" H2O - Designed to work on many popular tractors from around 375-450 cubic inches depending on operating rpm.
Threaded base (4 holes) use the common 2.68" 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:
Suggested Retail price $1099
We began production in mid 2019 and are now performing final assembly before shipments start. We will deliver orders as they were taken. These are high performance agricultural carburetors and we will not accept refunds.

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.
