Thanks! I yet have to try the manual start option...Wow............that thing is gorgeous! Congratulations on a well done restoration of a "usable" piece of machinery. By the way, it's a manual start also.....that's what that dandy rope pulley wheel is for. I had a Lincoln "Weldnpower" with the same set up, but manual start only, and it was easy to start.....usually. Unfortunately, it went the way of all things, gone through a divorce.
As for the propane, I don't see why it couldn't be equipped with the necessary regulators, etc. Any Kohler distributor should have the information.
It seems as though most of the Kohler engine dealers near me don't work on or generally stock parts for this engine. Would I have to replace the existing carburetor with a special one intended for gaseous fuels? I've seen on some larger kohler and onan generators that there is a solenoid valve connected before the regulator. Would I need one of these if I want to maintain the ability to remotely start and stop the generator? I'm sure that's a no-brainer, but I've seen propane regulators that have an electric priming valve on them.
