I have an SS322 938 series w/manual which states oil mix at 50-1 (2-1/2 ounces of oil to 1 gallon of fuel). NO methanol type fuel either. The spark plug is Champion CJ-8Y with a .030 gap.
Now... tell me this, are YOU having trouble with your chute not rotating as I am? I can't seem to see what's keeping it from turning from one direction to the other. If you care to stay in touch with someone who not only owns the same unit, but still has his owners manual, you'd be welcome to contact me using this email...
