I was helping my dad with his mclane edger last weekend and he mentioned a pair of generators he had in a shed that flooded. He claimed both were new, one "honda" and one "onan". We retreived the honda which was a honda gx390 powered Blackmax brand that I had often seen for sale at Sam's club. The onan, still in the box, had some stuff stacked on it so we left it for later.
I've hed pretty good luck getting most of my junk running after the same flood so I volunteered to take a look at it.
There was oil and water in the crankcase, a rusty liquid substance in the fuel tank and thankfully no water above the piston. I drained the oil, flushed the fuel tank (best I could) and cleaned the carb. I got it running breifly and then the fuel filter clogged. I then drained the milky oil again and refilled it. I replaced the fuel filter and fired it back up. After about 45 seconds the fuel filter clogged again and I drained the milky oil again. The oil was clearer this time and I noticed some (rust??) particles flowing out the drain hole. I got the bright idea to flush it out by spraying carb cleaner through thd fill hole while the the old oil was dripping out the opposite side of the block. The plan seemed to work out till I saw the red straw thing disappear into the fill hole.
It was getting dark and my patience was suddenly wearing thin so I left it for tomorrow. I'll try to work the straw out a little more tomorrow but I refuse to open up the case. Doing so will require removing the generator head from the tapered shaft which I'm sure is well rusted into place.
