They break down and cause all kinds of problems. will clog up everything in the fuel system. just have a look around the forum here you will see pics and all kinds of info. only cost about 50 bucks to do it but will save you alot in repairs. unless you lust enjoy taking carbs apart all the time and cleaning them i guess, lol
