Rob, There is very little you can do to "tune" a diesel. The timing is mechanically set and should not need adjusting for the life of the motor. The valves should be adjusted at around 500 hours. Hard starting, smoking, or reduced power could be dirty injectors. I experienced hard starting at 1,700 hours. One cylinder would fire and after a few seconds, the other would join in. I had the injectors rebuilt and now it starts in about 1 second. All 2 cylinder diesels vibrate to some extent. A bad motor mount can increase the vibration. There is a fairly easy way to check your mounts.. The only hard part is getting to the aft mounts. Using a crowbar and an assortment of scrap wood, lift up on each ear that the mounts are attached to. Release pressure on the crowbar and the engine should settle down quietly. If it clunks, then the mount is bad, or more likely, misaligned. No clunk, no worries. I changed all my mounts last winter and it was a BIG job. I did have one bad mount and I am glad I changed them. The result was only a very slight reduction in engine vibration. Don, #6293, M-18, Niceville, FL

To: [email protected] Date: Sunday, July 19, 2009, 1:09 PM hi all, is it possible to asses the condition of my diesel engine by feeling the vibrations through the cockpit sole or listening to it's sounds? i imagine that if it were out of sorts that it would be readily apparent.
