Just bought a 2001 RMK 600. The carbs were leaking fuel as the hoses on the bottom of the float bowls were cracked. While I had the carbs off I decided I'ld clean them and make sure all the pilots and mains were clean. Problem I am now running into is how do you get the float bowls to seal with only the 1 screw that holds the float bowl on. All the float bowls I've ever dealt with in the past had 4 screws. These are the stock Mikuni Carbs with the TPS. Any help would be greatly appreciated.
