Thanks for that word because it's apropos that the engine is idling and
surging periodically.

I don't think either of these California engines have an idle mixture
screw, as the engines are only about three or four years old, so it must be
the clogged passageways of the fuel passages.

I guess, in that case, Seafoam may be the trick as someone suggested.
Do you concur?

Or would you just run a few tanks of fuel?

I have a 5 kw generator and it did the surging while unloaded and around
500 to 1000 watts of load it would run fine. I drained out all the old
gas, cleaned the carborator some, and started using the ethanol free
gas. After running about 10 minutes it quit the surging and now idles
fine with no load.

I have started using the ethanol free gas in all the small engines.I do
add the Stable to the gas as an extra measure as it may be a few months
before I use some of them.
