I did service on a DPN30. Replaced the usual, fuel, air, oil filters. Ran unit back to work area no problems.
Just before leaving customer said it wasn't running good and trouble starting. I got on it and it started, ran but getting like a burning plastic(maybe) smell. Ran awhile, then parked it. Tried restarting, nothing. Cranks great, won't start. Checked fuel filters, checked fuel to cylinders, getting pressure at each cylinder, will not start. Fuses tested good. Oil level good.
So weird, ran great before servicing and right after then shortly nothing.
