I just bought my first SkiDoo and I could use some help getting it going. The sleds is a 2001 600 Grand Touring in visually perfect shape. I bought it from a freind who hasn't riden or started it in 3 years he bought it new and it has 1100 miles. He assures me that it ran when he put it away and won't take any money until I get it running again. I have a couple of questions. First is there a way to clean the carbs in place or do they need to be removed? I don't even want to turn it over until I'm sure they aren't gunked up. I've read too many horror stories about damage becuase of dirty carbs. Second besides a new battery what else should I be looking for? The compression is ~130 in both cylinders and the engine rotates freely with the pull start. The clutches have very light oxidation on them and the gas tank is empty. The Carbs are TM40's.

gotta remove them man, just 2 clamps then the slides unscrew leave them attached to the throttle cables then just the 4 screws to get the bowls off clean the main pilot real well make sure there no floaties in the bowls you should be mint. the other thing i would do is clean the fuel pump, believe there is like 8-10 screws to get it apart but be verry careful doing so where if you rip one of the diaphrams you will be replacing that. good luck

If it's sat for 3 years, chances are the crank bearings have gotten some rust on them, unless the previous owner fogged the motor. You'll have to remove the carbs to clean them,,,, floatbowls, mains, pilots, airscrews, slides all will need to come out, all passageways will need some carb cleaner and air pressure to be certain everythings open.

Your best bet is to go to an auto parts store and buy the gallon can of heavy duty carb cleaner cause
if those carbs are green the spray stuff will not cut it. Do a leak down test to see if the crank seals have
gotten dried out and are bad. Dump some rich premix down the cylinders and hand turn it over so some
of it runs down to the crank area and let it sit while you are doing the carbs. Make sure you have all
jets- pilots and mains- clean before trying to start the machine. The twin 600 is a good motor and should
give you miles of trouble free riding.
