It's supposed to be 4oz of oil for every gallon of gasoline, but I would be careful with that. I've been running that mixture in mine, and all it does is blow smoke and muck up the sparkplug. Now it won't start at all. Similar problem as yours -- it started once yesterday in the beginning with no problem -- I had to turn it off about 10 minutes later and it never restarted again. My fear is that the oil has either clogged something up or has flooded out some other part. There was a lot of oil and gas on the garage floor when I left it there overnight. Usually a new sparkplug and some starting fluid does the trick, but not this time..
