Late last season, my 2021 DF200 started vibrating and running roughly. It would not go over 3000 RPM, but this was intermittent, and it would run just fine for a few seconds, then go back to the sputtering. This led me to the assumption that it was a fuel issue, ie. water in the fuel, bad gas, etc. I put a bottle of HEET in the tank, changed the fuel filter.....no improvement. This spring, my mechanic changed the water separator, still not the culprit.
Are there any known issues with these symptoms, or is there anything else that I can try?
