I had an issue with my Autolite 2100 carb where gas was coming out of the overflow tubes. I assumed it was a stuck float. When I took the air horn off the float was down and pretty sticky to get up. Disassembled the carb and cleaned everything. Bought a rebuild kit and put it all back together. Started up fine but dies when you open the throttle like it is starving for fuel. Removed the air horn and adjusted the float to give it more gas in the bowl and now it starts but only idles...
