clean carb, new plugs, oil and filter, and air filter... starts and runs great. Borrowed a tachometer to spin on the generator end and brought it up to 1800 rpm, was running at 1600. Now I need my muffler to get here, if I was thinking I could have took this muffler to work and have one of the welders weld a new end on it, oh well new is on it's way. BTW Onan say 3.5 quarts with filter, mine seems more like 4 quarts with Fram PH3600, Spark plugs are Autolite 25's for now, can't find RS17YZ plugs anywhere locally, some said it's not a good number anymore?? Oh and the carb was horrible inside, hard to believe it ran at all.
