Not that familiar with Tohatsus but generally with autolube (which has a mechanical driven pump) I would try and figure out what the problem was before premixing.
You could be running lean with gummed up carbs which would increase the oil to petrol ratio and cause excessive oiling. Switching to premix if that's the case will not solve the real problem of gummed up main jets. If its been a while since the carbs were stripped and cleaned I would do that first as well as a compression check.
Also check the spark plugs are correct and/or replace maybe try non resistor plugs (may be ignition problem and weak spark).
