Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! First problem, the engine hard to start and has to use choke to keep it running, would seem to be a lack of fuel! Has fuel filter been replaced? Is the carburetor float bowl clean? The float and the needle valve is what controls the fuel to the engine. As for the second problem with the grass not clearing the deck, can be helped by keeping the rpm up in the engine and blade speed. Also oiling the inside of the rubber chute with a dry silicon lubricant will also help.
