⚠️ Critical Buyer Checklists (Read Before Buying!)
1. Controls Configuration: This spec uses a Dual Remote Control setup (meaning your mower must have two separate dash control levers—one for the throttle and a completely separate cable for the manual choke lever).
2. Exhaust / Muffler: Exhaust manifolds/mufflers are NOT included from the Kohler factory with replacement engines. You will simply transfer your mower's existing muffler assembly onto the new engine block using the new gaskets provided in the box.
3. Shipping Regulations: Due to strict local environmental emission laws, this specific gas engine cannot be shipped to California.
