This is an engine replacement kit for the Walker MTGHS. It is offered with a new Honda GX630 V-twin engine or a new Kohler Command CH740 engine. The kit includes what is needed to convert the machine from the old engine to the new one, unless otherwise stated.
The Honda GX630 has a two-barrel inner-vent carburetor for more precise fuel metering. Its fuel economy is similar to fuel injection. It has a hemispherical combustion chamber, a forged steel crankshaft and pressure-fed crankshaft bearings. A high-capacity pump delivers oil consistently, and a large air intake and high-efficiency cooling fan help with cooling.
The Kohler CH740 starts in all weather conditions, from 0 to 110 degrees. It has a standard 10% governor and an automotive-grade head gasket. Hydraulic lifters mean no valve train maintenance. The Kohler kit includes a wiring harness pigtail that simplifies the wiring, though some minor modifications are required. Detailed wiring instructions are provided.
