Hi, All. I have aKohler 15.5hp CV15S out of a Sears rider. I am trying to get it running. I pulled all the wiring harness out of the tractor. Figured out that I don't need much of it. However I am stumped by the red wire running to the underside of the carb into a small cylindercal shaped object. It that a fuel pump? The engeine will run as long as I pour small amounts of fuel down the carb. The other question that I have is I have two wires that run under the flywheel. What are they used for? How would I set this engine up so that it will also charge the 12v battery. Probably fairly easy stuff for most of you:)
