There is a special tool that fits into the clutch with a 19mm head on it so as to fit an impact wrench part no. 502541601, however you can remove it using a suitable screw driver, preferably the one that came with the saw, insert into one of the slots provided in the clutch, now use a hammer and keep striking the head of the screw driver to jar the clutch off against the compression of the saw ( keep deco valve out ) remember its a left hand thread so clockwise , it will eventually spin off

Not too difficult, remove the top cover, 3 screws, remove the air filter, 2 screws on the later filter, 1 single screw on the early filter, remove the fuel hose and blank off with a suitable bung, gently pry the choke out of the choke shaft ( this is a bayonet style fit ) remove the throttle wire by pring it up and out of the throttle lever,now use a 4mm allen key to remove the two carb securing screws, you will need a short allen key to remove the lower l/h screw, the carb will now come away be carful not to lose the gasket, the induction block will also come away from the back of the cylinder. there will be another gasket here., all these components will have to be aligned to re fit the carb.

I think you have one of two things going on hear, an overpressure problem or a carburetor issue with the engine.

The T screw is the engine idle screw, screw in ( clockwise ) the idle will increase, unscrew and the idle speed will decrease.

The big pulley is driven by the engine via a belt, if the pulley is loose on the shaft then either the pulley or the shaft needs to be replaced, as the pulley is a softer material then most likely the pulley, if the shaft is moving up and down in the gear housing then the bearing has worn in the housing this would mean the two half's of the gearbox need to be parted, quite a large job.

Turn the saw upside down, on the clutch half of the crank you should see a 5crew head which can only be accessed from the bottom of the saw. There may also be a pictogram of a cutter with an oil drip and a + and - next to it.

Maybe drawing air into the system, check the fuel line, carb and gaskets
