CULMKARI Carburetor for Kohler 7000 Series 22–26HP Engines — Fits KT730–KT745, Includes Gaskets, OE-Fit

CULMKARI replacement carburetor engineered to restore fuel delivery and performance on Kohler 7000 Series engines (22–26HP) including KT730, KT735, KT740 and KT745 models, supplied as a complete kit with gaskets.

When a vintage or in-service Kohler small engine runs rough, floods, stalls, or uses too much fuel, the carburetor is often the cause. This CULMKARI unit is built to match Kohler OE dimensions and replace common part numbers such as 1685321-S and 3285361S. The kit includes the gaskets needed for a straightforward swap and is intended for 22–26HP engines in the Kohler 7000 Series and select KT72x–KT74x models. It’s designed for mechanics, landscapers and do-it-yourselfers who want to get equipment back to reliable operation without sourcing multiple parts.

How will this carburetor improve engine starting and idling?

Installing a properly matched carburetor restores correct fuel-to-air ratios for cold and hot starts, reducing hard starts and erratic idling. The calibrated fuel circuits and fresh seals prevent air leaks and flooding that commonly cause misfires.

• Replacement for Kohler part numbers 1685321-S, 3285361S and equivalents.
• Fresh gaskets stop vacuum leaks that upset idle speed.
• Pre-set fuel passages tuned to typical Kohler 7000 Series flow characteristics.

Will this fit my Kohler 22–26HP engine and how do I confirm compatibility?

The carburetor is compatible with Kohler 7000 Series 22HP–26HP engines and several KT72x–KT74x models including KT730, KT735, KT740 and KT745. To confirm fit, compare your engine’s part numbers and mounting flange to the listed replacements before installation.

• Verify your engine model and serial plate match Kohler 7000 Series or KT730–KT745 listings.
• Cross-check OEM part numbers: 16 853 21-S / 1685321-S / 3285361S.
• Confirm bolt pattern and throttle linkage orientation at the manifold.

What comes in the kit and what tools or steps are needed for installation?
