At 10 hours the engine threw a rod...the welch plug fell out of the crank and the engine lost oil pressure..
Is this a warranty ???
Your'e the warranty expert. You tell me! Better yet explain to " Little Billy" how a welch plug fell out of a new engine, warranty or not! " Cause he ain't buyin' the line about improperly stored and corrosion loosening the plug!

Actually its not covered under warranty.

Still not charging...

Since no fuses in the charging circuit on most Kohlers, I'm going with bad ground.
Or faulty regulator, or, loose connection, or, open alternator, or...............
Where's my ribs!!!!

Can't be a bad carb, I know where they are made...
You got it...I've actually had to put 3 gaskets between the breather cover and the carb to get it to seal..
I got in the habit of checking the carb throat as I pumped the primer before installing the air filter..
