follow the throttle cable to the throttle you should see three screws one going in to the throttle if you tighten this up it will give you a few more revs but if you want more you will need a friend to help you first you need a screwdriver or a allen key start the engine and give it full revs locate the screw you just tighten look slightly bellow you should see two more screws tighten them while you are giving it full revs you should notice that if you tighten them it will give you more revs and if you losen the screws the revs should be less but don't give it too many revs because it will get to hot and catch fire give it anough revs so you are satified if this dosnt work try taking the air filter out and starting it if it runs better than before the hedgetrimmer was being choked or the air and fule mixture is wrong and you should drain the petrol out and take it of by taking the pullcord of the petrol can should fall off clean it out with air compressor clean it all out

I have the same problem, I think its a fault with this item.
Give up and buy a new one, but not a McCullock.
