Backed out of the garage 2 days ago to clean the garage, then pulled the alty back in. Yesterday went out and it wouldn't start. It was cranking like it wanted to, but wouldn't turn over. Gave it about a 20 minute rest - went back out and after cranking a little it started, but it smelled like it was flooded. Almost an oily smell. I dont usually hit the gas pedal when I'm starting it, so have no idea what that was all about, and am really baffled, as it behaved for all my around town stop and go afterwards. Had it in the shop for some sputtering this past winter after a particularly frigid few days. They said they couldn't find anything wrong, probably just some moisture in the fuel line. No aftermarket anything on it and only 13k miles- any ideas?
