I bought a used 2010 Gravely promaster 148 with 19 hours on it. I have put a couple hours on the mower since I got it and it has ran fine. The person that I bought it from had it sitting outside at the mower shop where he financed it for quite a while its been sitting out there. When I bought it I put midgrade gasoline in it and a bit to much stabil (which I know wont hurt anything). My question is this after sitting for a week without running it when I went to start it earlier why did a big cloud of white smoke come out only lasted for a second then it was fine could it be bad gas or is this going to be a problem IM gonna start seeing after I saw the smoke i ran it for a while with no problems IM stumped. Thanks for any input. Oh yeah I changed the oil when i first got it and its not overfilled. I didnt drain the gas before I added the midgrade either maybe water from sitting out side or the fuel to rich?
