We have a 02 sportsman's 500 ho. Worsted buy! She begged zero balls. So we have now replaced the cam. But now the carb is filling the air box with fuel... so my question is... how do you know when theres nothing you can do to fix the carb. Someone is telling me if the diaphragm is missed shaped on one side it means theres hair line fractures.

We have never worked on carbs!

Thanks for helping a newbie guys!

The diaphragm can be damaged by poor fuel and improper cleaning or incorrect maintenance, but almost all carbs can be repaired.
