    How about this for a lucky break: I had the 320C running for about 10-15 minutes and it was running fine until I stopped for a minute and it throttled down as per usual then went to move again and had no power and a whole lot of black smoke being emitted from the exhaust. On further inspection...

    Lucky escape!

    Got called out to help get this tractor and trailer out of this predicament, it's fair to say that buddy got a little closer to the edge than necessary!:eek: Took about 3 hours to extract the rig from its dodgy parking spot.
