The only way to add more fuel is the "locked torque screw" It has individual Bosch mechanical fuel injectors. Hard to believe he could have run it hard enough to damage, but I suppose if fuel was maxed out with the screw, eventually egt's might have gotten high enough to damage. Before I turbocharged mine, uphill with 30" tires and 2 people , I could see egt's slowly climb above 1200F. After turbo, egt's dropped way down. I ran it this summer at 45-50 mph for at least an hour, keeping up with my 700 TRV, no problem. It is a Kohler motor now. Kraft Power out of Massachucetts sells and services them, also Kohler sells it as a generator motor and a marine motor. Try Country Cat to download a parts and service manual. Also <mymowerparts.com> . 1 thing that I've seen with diesels that were overheated or run with excessive EGT's, blown head gasket. It's a stout motor, but letting his brother in law ride it..... Possibly, Arctic Cat might have a replacement motor somewhere in the pipeline, that they would sell at a good discount. There is a guy on the Dodge Ram forums whose motor failed at just under 500,000 miles and Ram gave him a new motor, you never know. BTW, these motors have very high compression, even for a diesel.
