maybe if you guys can make this a sticky on the forum??


For those of us who forgot to winterize..............


Find a wire bread tie or a .10 guitar string
using a wire bread tie melt away the plastic coating so that you just have the wire. straighten it.

remove the carburetor then remove the bowl from the bottom of the carb.

tap the side of the bowl with the handle of your screwdriver once you have the screws out so that the gasket will let go without tearing and you can reuse it.

the jets are the round brass pieces in the bottom of the carb.
use the wire bread tie or guitar string to run through the jets one at a time.
on the needle jet you'll need to press the thumb throttle to get the wire through it.

once you are done, carefully remove the floats via the pin that they pivot on.
be very careful not to lose the float valve as they are expensive to replace.

please note how the floats were sitting before you took them out.
you don't want to get the floats back in upside down as it will just overflow and cause it to not run properly.
once you have the float off and the float valve removed, inspect the float valve for wear.

also inpsect the floats for cracks or holes.
if there are holes or cracks replace the float, if the float valve is worn replace it.

inspect the hole that the float valve came out of for dirt grime or fuel gum. remove any you find.

remove the choke cable and plunger, inspect the hole it came out of for gunk. clean out if necessary.

finally reassemble the floats, and put the bowl back on.
reinstall the carburetor.  
Keep it RUBBER SIDE DOWN!!

Going to add some info., I hope that's okay wolf1.

If your atv was running great before you needed to clean it. When you have taken the carb off the atv, turn the pilot jet in until it Lightly Seats, record the amount of turns to Lightly Seat. Then you will know how many turns to go back out with the pilot jet.

If you are replacing or cleaning needle jet, record the clip position (if applicable).

Hopefully this will help carb. newbies.
