i think i have 2 problems i just bought this sled 1200 miles was not driven since winter of 04/05 dealer had set it up for storage .after sitting for 1 or 2 days it starts fine but will not move if you rev it up smells like belt is burning, if i lift the track off the ground and rev it up to about 7000 rpms 2 or 3 times then it takes off at about 4800 to 5000 rpms. but as you drive, it bogs alot . it seems to bog at very low speed or from a stop of if you let off and then accelerate.the engine feels like it going to cut out.engine does not rev up . but then it takes off and runs fine .carb rebuild ? clutch ?. if i do need to clean/rebuild carbs do you need a kit,or can you just take them apart and clean. and is there a way to clean the clutch? also is there a place on line where you can get instructions on rebuilding the carbs/clutch.
