There is no correct oil/fuel ratio for the TS100 unless the motor is split and the oil slinger plate removed. If you simply disconnect the oil pump and run it premix the left side main bearing and the big end assy (conrod/crank) bearing will starve for oil and thus cause considerable damage over due time.

Around 25 to 1 should work OK.
2 strokes that have plain bearings in the power unit (for example - conrod small end bush) usually use an oilier mix. Your Suzuki engine would have rolling bearings throughout I think.
