I have a 1996 DT25C that is running rough. It had some trash in the carbs that was cleaned by my local dealer this past summer and it ran better after that but it is still not running right. I have since removed, cleaned, and inspected the carbs again with the help of a service manual. All the measurements are right and they are super clean. My fuel is good, I can't find any air leaks, and my tank vent is open. Before all this trouble started, it had almost a "fast idle" type feature when you first started it up. Since my problems started, it has not done that and it is still running rough. It will run like a champ wide open but as soon as you let off the throttle, it cuts off. I am thinking this is the engine temperature sensor gone bad? The manual says it does advance the timing for 15 seconds when it is cold and for 3 seconds after it is warm to help with starting. What is the best way to check this or can it be something else?<br />*By the way, this board is great. I have learned alot about my engine as well as the mechanics of how it works over the past few months and have enjoyed tinkering on it. Thanks for all the help.
