Stihl MS 211/c idle issue

Thanks for the reply. I will mix some new fuel/2 stroke at 50:1 and make sure it's spot on and check all the linkages on the carb. It does seem to be just an idling problem. If I rev it, it seems to pick up the revs okay. I did check the piston through the muffler port and it was a little oily, black oil, but no scoring.

Just thought I would post an update on my Stihl ms 211 issue. Used the clues to my issue from Spudulike with some more research. I don't have testing equipment so I was guessing. I pulled the carb and gave it a thorough clean with carb cleaner. Took the limiter screws out and the needle, lever, spring and diaphragms and noticed thar the metering lever was set aout 1mm to high. I reset it to the correct height using a new carb kit and did see some debris in the pool of carb cleaner in the container after cleaning. Limiter screws were set to factory settings. I'm guessing that the fuel residue coming from the exhaust and the excessive white smoke were signs that it was running to rich due to the wrong metering lever height. I started it up and ran it for 10 minutes yesterday and today and so far the non idling issue seems to have gone and there is far less fuel residue from the exhaust and far less white smoke. Next thing is to see how it performs in the cut. Fingers crossed.

Glad the early signs are positive.
