onan generator convert from gasoline to propane

How much should it cost and how difficult to convert my Onan genset 4.0 to propane. It is carburated.

Not sure how it is done, but my Kubota dual fuel generator has a plethora of hoses, regulators and distribution stuff for the propane. Gas just runs to the carb like a lawn mower. However, look into it further, as you won't regret it. Fill the gas tank every two hours, or let it run for days on propane from a larger tank (100 gal+). You may have to get a conversion kit from Onan to have a perfect fit.

I second the motion on contacting Onan. Something as simple as the wrong sparkplug can cause problems.
