It's an Onan 4CCK-3R/1J 1800 RPM, 10 HP,
2 cylinder, gasoline, 3.5 KW, 4 KW surge,
from 1965 with 57 hours use on it.
In the 2003 Northeast USA power blackout,
it ran two homes, including two refrigerators
and a freezer.
Perhaps not a home-size unit, but the
advantage is that is sips gasoline

Probably the ones I've had the most luck with are the Islatrol series from

or one of the other companies that have power divisions

Hello to group,
Is putting a MOV from hot to ground, neutral to ground, on the primary of the
