Nothing happens no matter how far I adjusted it, even all the way in. Still puffing black smoke. Found a new mixture screw in a rebuild kit going to swap them out, Don’t have much faith that will solve problem ... Only thing left is the needle and seat. Otherwise it's $300 for a new carb.

Hahaha....sorry I couldn't help you... BTW... you have one of the few carbs that the mixture screw is accessible... Most are covered with a Welch plug or are a fixed jet ( non adjustable).. you will never find any reference to that screw or the adjustment in any Kohler literature..

One last thing, make sure the governor is set correctly. Take the black link out in the picture, push everything to WOT. The throttle linkage to the carb should fall in the hole of the governor arm. If not, it is not set correctly.

I put a tach on it to see the rpms and I adjusted the idle to 1500 rpms (after warm up), I adjusted the low needle (i replaced the old one) and at full throttle I was only getting 3400 rpms with no load. I adjusted the governor up a notch but it didn't do much. If I pull the linkage on the carb I can get the rpms up but the linkages where the throttle cable attaches to are at max.

I have to think its a fuel problem because under a load at higher rpm it runs great.The only thing I have not done is get a carb kit .Usually that only contains the gaskets and a float needle but I may have to do that. Has anyone got any thoughts? Thanks ... Did the problem show up after the ignition system was changed, or is this something more recent? Its possible you got bad parts. Also, check the connections on the Smart Spark system and make sure they are absolutely clean. I had some running issues with a Kohler at the shop that ended up being a dirty/corroded connection at the Smark Spark module.
