Hello all I've got a bit of a problem with my trusty climbing saw, (Stihl MS200T, 2008 model). It doesn't want to tick over nicely at the moment. When I first start it the idle is a bit uneven and after a while it cuts out altogether. When hot its even worse, it just dies as soon as I release the throttle. Apart from that it seems fine, it revs as good as ever and has plenty of power for cutting. I should mention that I may be responsible for this problem! A couple of weeks ago I was doing a reduction on a leylandii hedge, and using a skip to get rid of the waste. I was getting short on time and skip space so decided to mill the brash down a bit with the chainsaw. I went at it pretty hard and after only a few minutes the saw started cutting out on idle. I figure I must have overheated the poor thing as it was a stinking hot day and the exhaust was pretty stifled as I had the bar in the brash up to the hilt. The exhaust housing was smoking afterwards. I feel a bit stupid writing this now! I'm loath to take it to my local service place again as I feel that since I'm normally pretty mechanically minded this is something I should be able to sort myself. Judging by a lot of other posts I've read on here I reckon this is the best place to come for advice as of few of you blokes seem to be chainsaw Oracles! What does anyone think;- have I indeed overheated the thing and caused some damage to something? (or maybe the smoke was just resin burning off on the exhaust. He says hopefully!). Or is this just a question of re-tuning the carb? If anyone could give me a quick tutorial on the three screws that would be much appreciated, (H, L and LA). Thanks. I've always wanted to get my head around these but never plucked up the courage to fiddle with them in case I muck up a fine balance of something. Thanks in advance. Sorry about the long post!

Does all brushcutters/strimmers like mine have only one carb adjustment screw? What is my one for?
