Its very easy. Just remove the slide from top of carb, loosen the clamps. Then wiggle the carb out of the boots (you could just turn it so the bowl faces you, but I much prefer taking it out). Take off the float bowl via the 4 phillip screws. The float will be lookin right at you! CAREFULLY remove the pivot pin that holds the float, it just pushes out. Then lift out the float and valve, and blast the entire carb really good with carb. cleaner. Might as well clean all the other jets out while you're in there. Make sure the rubber tip on the needle (comes out hanging on the float) isn't worn out or torn etc. Reasemble and check the float level, adjust if necessary. Thats it! Put it back together and crack open a cold one. ;)
