OK, I don't know how to spell sedintary, but my motor has been sitting all summer while I built the house, has not been started since early May, with a full tank of fuel still hooked to it. It is a 25hp tiller, pull start. Question is, do I need to do anything special before firing it up? Should I get new fuel first, and what about the fuel in the hose? I sure hate to throw out a full tank of gas, as much as gas is now. I did mix sea-foam with the gas/oil that is in the tank, but do not think I put stabil in that time, bacause I was out, and did not expect it to have to sit all summer. Thanks everyone!
