Need to know model year of my Suzuki DT30C. Cannot find from reference charts - number is just DT30C, no other letters. Serial number is: 03003 906019. Photo below. Can anyone tell me what year this is, or point me to a reference table? Motor is not running smoothly and stalls out often between low idle and giving it some throttle. I suspect fuel related as the motor has not been weatherized over cold winters for several years (before I owned). Once I know the model year, I will move on to figuring out what my next steps are. I am a new member as of today.
