Just bought a 2013 b2650 today. I had to drive 3 hours to get it. Ran great the entire time I tested everything at the guys house. I get home and after about 10 minutes it stalls out and runs rough when I restart it. Seems fuel related, I add a few gallons of diesel but no luck. Did I adjitat the fuel or something? Not sure what to check first. Thanks for any help.
