How do I confirm this carburetor will mount correctly on my tractor?

Mounting compatibility depends on the bolt center distance and choke/throttle size. Measure your existing carburetor mounting studs and compare the air horn dimensions against the specs below to ensure a match. If bolt spacing or diameters differ, the unit will not seat properly.

• Mounting stud spacing: 2-3/8" center-to-center — not compatible with 2-1/2" spacing.
• Throttle body throat diameter: 1-1/16".
• Choke air horn outer diameter (OD): 1-5/8"; inner diameter (ID): 1-3/8".

What condition and assembly should I expect out of the box?

The THUNDERMINGO carburetor ships as a fully assembled unit with critical components adjusted for basic fitment. Each part is manufactured to close tolerances and inspected during assembly to reduce setup time at installation. It is recommended to inspect gaskets and linkages for wear and replace as necessary during installation.

• Delivered fully assembled and tested for alignment and basic function.
• Precision-manufactured components for consistent fit with original mounting points.
• Inspect and compare to original unit using product images before installation.

Will this replacement require modifications or additional parts?

Most installations are bolt-on when the original carburetor has matching dimensions. However, you should be prepared to swap gaskets, clamps, and possibly linkage hardware if your original components are worn or nonstandard. Measure hole centers and confirm throttle/choke sizes to avoid surprises.

• Prepare to replace gaskets and seals for a leak-free installation.
• No machining required if bolt spacing is 2-3/8" and choke/throat dimensions match.
• Contact seller with photos if uncertain about fitment before purchasing.
