I have a 2001 Dixie Flatlander. I was wondering if there was a certian way to properly shut down the engine. The owners manual says to Idle down then shut off, like a other traditional mowers I have had. A local guy told me that they had electric fuel pumps and that they shut fuel off delayed after you turn the key. When Ever I idle down then shut it off, it back fires, when Ever I leave it open it shuts down just fine. Sounds better, and doesn't Back Fire. Any comments.
