Okay Ski-doo experts...as the topic suggests, my 700 is running on one cylinder when off the throttle. I went on a 110 km ride yesterday, and at the 75 km mark we shut down for a tea. After start up, I noticed that the sled was idling on one cylinder. I threw in a new set of plugs, but there was no difference. Both older plugs were running a nice brown. From 1500 rpm to 3000 you can tell that the engine is missing, and after 3000 the sled picks right up. I'm running new fuel and isopropal. I've checked all wiring connections and they look good. The mileage on the sled is 700km. Any ideas what the problem is????? Thanks in advance..
