Been Having issue with this for a couple years. I use this machine and it wants to stall when the gas is about 1/2 way empty or so, but only when the blades are engaged and more so when going up hill. My brother thinks its a tank design issue, but In doing research, I have not found anyone with similar problem with this machine. could this be a just a fuel line problem? Also the pulleys seem loose in the deck when it is in disengage and the pulles seem loose as well. when I disengage the blades, the rod that connects to the blade lever grinds on the pulley near it. Everything tightens up when the blades are engaged. It also wants to pull th the right when mowing and i'm constantly using the left handle to keep straight. any thoughts or suggestions?
