Got my 8 y/o riding an '06 300 Freestyle e-start and reverse. The round ring holding the key assembly on must have got loose and then came off. The whole assembly fell down in the hole, key and all.....luckily it was turned to the "on" position so we could at least pull start it. My 8 y/o isn't strong enough to pull start it, so I need to get it fixed. Are there any special steps to getting to this that I need to know? This is our first freestyle and basically first Ski-doo (got a Summit coming too).....haven't ever worked on a Ski-doo yet. Sled will be coming out of storage to get ready for season, any help I can get would be much appreciated.THANKS!!
