I've been fixing up this old Kawasaki I bought that wasn't running, all I did was take of the carb and replace the jets and gaskets in the carb and float needle. I got the bike running for about a week with no real issues. Then the bike started pouring out gas in the 2nd carburetor. It was coming out of the nipple of the bottom of the float bowl. I took out the carb and there was a bit of stuff clogging the needle so i cleared that out, but the carbs back in and it stopped. Then It started doing the same thing out of the 4th carb. I took the carbs out again and cleared everything out and it still was pouring gas out. I have since cleaned all the carbs again to make sure absolutely nothing would clog them but the 4th carb still leaks gas out of the nipple at the bottom of the bowl. Anyone has any similar issues that knows what I need to do to fix it?
