Question about Garden
Check the engine running (it should 4-stroke at speed when not cutting, but will immediately 2-stroke when cutting) after removing the bar and chain. If the engine seems ok now, check that oil is oozing out of the engine side port. If ok, clean the oil ports at the drive end of the bar including the two small ports that go out to the chain groove on each side, then clean the entire chain groove. Oil the end sprocket (if it exists) and check it's turning. Reinstall the bar and chain, and adjust the chain until it just stops drooping from the lower bar, but not so tight that it can't be turned by hand. If no oil came out of the engine port in the first test, then troubleshoot the oil pumping system from the oil tank filter to the oil pump itself. The chain should cut at any running speed, just not as fast. Make sure that it is properly sharpened. Clean the air cleaner and the muffler if either is plugged. If you have further problems, suggest taking the machine to a Stihl repair center for carburetor service if needed. Hope this helps!
