I just picked up a brand new Stihl FS 250 brush cutter yesterday to tackle an out of control area of my property. When running at operating speed the thing is an animal and runs great. The issues I'm having are while idling and coming off idle. When I start the cutter on the ground it will idle properly initially. When I pick it up to clip it to my harness (not touching the throttle), it will bog down and stall. After running at high speed for a while, it will stall shortly after coming back to an idle. I've noticed that I can affect the speed of the idle by holding the cutter in different orientations.
My other problem is the engine bogs down and will stall if I'm not careful at metering the throttle while the engine is idling or running at low speed. None of my other 2 stroke tools have issues like this (MS361, large Husky backback blower, light duty echo weed wacker). They all run perfectly regardless of orientation and you can hammer the throttle at idle and they rev up with no bogging or lag.
My FS 250 has an adjustable carb with high, low, and idle screws. I played around with the idle adjustment but didn't notice a kind of change regardless of the direction I turned it. My dealer is closed on Sundays and my work schedule makes it hard to get there during the week so I'm trying to see if I can tune it without bringing it back to them. Any insight or instructions would be great!
Also, all my 2 stroke tools run off the same mix. Just in case I made a fresh batch of mix with premium gas but it made no difference.
