I found this forum while searching for possible mod's on a few Kohlers i've aquired from work. I'm not a racer, I'm a gold prospector. I run a dredge homebuilt for the hobby that consumes me (gold fever). The day job is a rental yard man/ wrench turner for a constrution sales, service and rental company. I have aquired several engine's for free from work some need work some don't. I have a Kohler Comand Pro 14 that i'm going to work on first, just looking for more torque. The second is a Comand Pro 20 lp gas brand new never run cracked base. I'm here to learn and ask question along the way,
