They went right in like the originals did and set in no time. Quick and easy. Carburetor bolt fills as it should without overflowing.

Installed these in a proform 850 carb that was dribbling fuel through the main jets at part throttle with 6 psi of fuel pressure. The original float valves were .150. These smaller valves seal better. It eliminated the part throttle acceleration blatting exhaust sound too.
