RE: Carb tuning
Plain and simple 32 parts gas 1 part oil Now take that and go 50 parts gas to 1 part oil. You are deluting the oil by adding more parts fuel, which will run leaner. You can never go wrong by adding a bit of extra oil, most you might do is foul a plug. But others will tell you too rich is not good either which is true rings will start sticking and carbon deposits are not good either.
