how can I fix my Ryobi wipper snipper?

if you are having trouble initialy starting it the problem is most likely that high reving has vibrated out the high and low[idle] speed mixture screws; the end result being very high revs but loss of power, and therefore a lot of stalling in long grass; remedy the problem by locating these screws, winding them both in fully and then out 3/4 of a turn, start it and adjust the idle screw then depress the trigger fully whilst adjusting the high speed screw, listen to the engine while doing this as it is crucial that, on high speed the engine should sound as if it is labouring, [must be slightly rich fuel delivery]then stop the engine and repeat the proceedure but only to fine tune and away you go bud;
