My Spitfire has a too high idle as well as a stuck automatic choke. While most people toss the poor Zenith Stromberg carburetor in the trash I thought I’d give a shot at cleaning it up and making it function. I’m not sure if it will fix the high idle but a working choke would sure make starting it easier. The starting point is rather grim looking.
The carburetor is of. That log style intake manifold can’t be the most efficient …
The Zenith Stromberg carburetor cleaned up inside and out. The water choke arm now moves nice and smoothly. Now it just needs to go back on for testing.
