Just noticed my new Dixie Chopper XG2703-60 that has only 13 hrs. has a red glowing muffler, just noticed tonight after I got done cutting yard about 10:00pm . This is not just a little section of the exhaust but the whole entire muffler. Just wondering if this has occured to anyone else with new mower or if any adjustments are needed to fuel enrichment ??? Kinda makes me nervous to run this mower like this.
