Kohler carb recommendation?
 

I have a 782 with a KT17 series II engine. It has been running great until this weekend. It was surging really bad and would only run on full choke. I pulled the carb off to clean it last night and noticed that it has a Walbro carb. I would like to replace it with the more adjustable Kohler unit. Which Kohler carb should I be looking for?

Just get a carb from a series I KT-17. I believe a #26 will also work if you change the throttle and choke arms.
