How can i fix my Marunaka power reaper with mitsubishi T50 engine?

I hope this helps - but I've never heard of this particular machine....anyway, the screw marked L is for low speed running - that is, the engine running at tickover. The screw marked H is for high speed running - that is, at maximum speed. GENERALLY both screws are set at about 1 turn out from fully in. If the engine will run slowly, turn screw L a little bit until the engine speed tries to pick up. With the engine running fast, dont adjust screw H unless the engine starts to splutter a bit - if it does, screw H in a fraction. Make sure that the air cleaner is clean first though.
