I have an old lawn boy lawnmower that my uncle gave to me last year and it still runs but you cannot adjust the height and after a while it over heats. So I bought a new lawnmowwer. The lawn boy uses a gas oil mix and the new one does not, so now I am stuck with some gas that I do not need. How can I get rid of this without trying to burn it up? Is there anyplace I can take it? Obviously I don't want to just dump it. Any info would be greatly appreciated.If interested I am going to call my uncle and see if he wants the lawnmower back(doubtful).So I will just give it to some body if they want it. Like I said before it runs pretty good you just can't adjust the height and it overheats after a while.
