Just bought a Craftsman 46' Turn Tight Lawn Tractor with the 22HP Kohler Pro Courage engine. It says in the operators manual that I should consult the 'engine manual' for specific engine adjustments & specs like carb, throttle cable, choke adjustments, etc. I have the operators manual and the repair parts manual, but didn't get the Kohler engine manual. All the lawn tractors/riding mowers I've bought over the years come with 3 manuals: operators/owners manual, parts & repair manual, and an engine manual. I'd like to get the 22HP Kohler Pro Courage engine manual that was mentioned in the owners manual.
