Exclamation Walbro carburetor problem

I have a Cub Cadet lawn tractor with a Kohler Courage 19 engine. Untreated fuel was left in the carburetor over the summer, a four-month period. The tractor will not start. There is fire, but no combustion. Does anyone know where I can obtain a diagram of a Walbro LMK carb? I suspect the float system has shellacked and will not allow fuel into the carburetor. Is there an easy way to flush the float system without tearing the carburetor apart?
Thanks for any help you can give.

You can enter your engine model number below and download a full service manual;

Service & Owners Manuals - Service & Support - Kohler Engines

I would suggest a complete carb tear-down and clean as outlined in the manual.

Good Luck
