So My Ski Doo Rev Summit X had a meltdown last year it caught on fire for maybe a minute, before I was able to put it out, The sled is at the dealer right now and there saying it needs a new set of carbs which is 73 different parts very few of which are plastic and or rubber, so my question is do they make rebuild kits instead of paying over $900 for a new set. The sled is 2007
