I found a local "generator whisperer guru" who changed the oil, and tuned it up. It didn't run well before and has run well in the two years since. It is important to run it every few weeks or so under load.

Regards,

Mark

Periodically running the genset under load is good advice. However, "every few weeks" is a bit of an exaggeration. This is especially true with the propane version of the genset, for which this is much less important than with gasoline units. In my experience (14 years and two rigs) a few times/season is adequate to keep the commutator surfaces clean. If I had gas, I would do it more often, to avoid carburetor issues. Generally speaking, the propane units are less trouble-prone than gas.
