There is a broken spring on the choke, causing it to run really rich. I’ll have to plow through the parts manual to see if we can find a replacement spring.
The broken spring is actually part of the mechanical governor on the engine. I found a description and drawing, but no part number, in the Kohler Engine Service Guide. If someone is out at the field in the next couple of days and can get the engine Model and Serial numbers for me, that would be most appreciated. I need the numbers off the engine, not the mower (I have those). This is for Hustler #2, the newer one, parked closest to the garage door of the hangar on Monday. Thanks. Just e-mail, text them or post a message with the numbers, please.
