As for the generator, I continued to have problems with the oil being pulled back through the air cleaner

I have rebuilt a lot of small 4 cycle engines. Their intake air takes the "path of least resistance". If they can't get what they need through the air filter, then it has to come from the crank case breather tube. There are some dirty oily vapors in there which in a short time will foul your filter. Change your filter often. Paper filters clog with dust and cannot be cleaned well enough after a couple of cleanings. Cheap insurance, like the commercial said "You can pay me now (small amount for filters), or you can pay me later ( large amount for overhaul). Change the oil and filters often and if there isn't an inline fuel filter, put one in. Biggest cause of engine problem is dirty or old stale fuel. Good Luck, you are becoming an involuntary expert quickly.

I hear ya. FWIW, it still seemed like "clean" oil. The filter is foam, so I would simply squeeze it out (wrap in a couple of paper towels and squeeze) to get the excess oil out, wipe down the inside of the air cleaner housing, and put it all back together. Since there wasn't a lot of strong airflow into the fresh air opening, it didn't seem to be sucking in a lot of dust, so the filter still looks pretty clean.
