The push button starter won't engage to start the motor so I have to pull start it. Also, and more important, the transmission will not engage in any gear forwards or reverse so I have to push this large 24" snowthrower. If this extra info helps so I can get this fixed i am adding it. 24" width, 5.0 HP, Engine Family: XTPXS.1951BF, Displacement: 195. Thank you.
