I was in NY during Irene.
I was caretaker for my grandfather's house while he spent his last year in the VA in-residence facility. He was a tinkerer and somehow managed to acquire a VERY old Onan generator along the way. I found it wrapped up in the corner of his carport. I checked and the oil was clean and I left it alone until Irene was looming.
My cousin and I decided to fire it up just in case. We needed to replace the breaker and futzed with the points. It reluctantly fired up and ran poorly for a while until it finally worked itself in after sitting idle for so long. Poured a can of seafoam in the gas and let it run for a while. Lucky thing because the trees fell over the power lines next door and we had no power for six days. Since the road was blocked I ran extension cable s across the street and powered my cousin's refrigerator, freezer, TV and satellite as well as various lamps at their house and the refrigerator and lights at mine. After a couple days I realized the water pump was 110 instead of 220 so I pulled the wires and installed a plug on them and ran that as well. Ran garden hoses across the street and back fed the cousin's house through the hose bib on the street side. We both had water and electricity thanks to that VERY old Onan until the road crews finally came and removed the trees and restored commercial power.
After that we mounted it on a cart and scrounged up a fuel tank (had been using a propped up gas can with a hose on the vent for gravity feed as the fuel pump did not work) and they are still using it around the farm!
My other cousin up the street had water in the basement so I parked my RV up there so she would have electricity to keep the basement pump working. Shuttled the RV up and down the street to keep the neighbor's freezers cold. As long as they kept them closed they would last for several hours while I ran it at the next house. Worked in a pinch!
Should have seen the look of pure joy on the old man's face when I told him all about it!
