Kohler CH20S Command not running right.
Hi, I have a Kohler 20 horse motor on a Walker mower that won't idle at all and doesn't have much power at all. I rebuilt the carb with the few new parts that come in a rebuild kit for these. The only way to get it to run somewhat smooth is to run with the choke 1/2 - 3/4 closed. There's not much going on inside the carb of this machine and its been blown out, cleaned with carb cleaner, soaked, blown out again and still runs like crap. Any ideas on what to try next before I spend $380 on a new carb? Also this motor has no accelerator pump built into it. And the motor is probably a 2000 or so.
