Autolite 4300 4 Barrel Power Valve 56-3

Power valve fit perfectly. Good quality. Haven't started car yet, still some finishing up to do.

Exactly what i ordered and fast

I broke my old power valve while rebuilding my carburetor and Mike’s power valve worked great. No issues.

When I went to rebuild my carb I noticed that the spring and retainer cap for my power valve were missing. The rebuild kit came with a new retainer cap but not a spring and I didn't know what spring to use to replace it. I ended up buying this and replacing the entire power valve. It was totally worth it, the new unit is much smother, the old one was worn and felt as if it was binding. This one is much nicer it works perfect.

Always felt the car was sluggish on a hard acceleration. The new power valve corrected the problem. Great part and easy ordering.
