Have no fear.
As Johndoh said, "Glort is a multi talented and knowledgeable individual he's never going to tell you anything that's not true." He might run on a bit, but won't give you a bad steer.
I squirt about 1 liter of water into my 6/1 every so often to keep the innards clean.
Been doing it for almost 7 years. Does not even slow it down. I do it when running a fair load on the generator.
It works fine. give it a try.
Cheers
