The Place for Model-A Ford Carburetors

After installing a carburetor, it needs to be road tested to check its performance.

Testing Newly Installed Carburetor

  1. Start engine using Starting Procedure.
  2. After the engine has warmed up, perform Carburetor Idle RPM and Idle Air Mixture Adjustment.
  3. Test drive vehicle to verify that engine idles well, engine accelerates without hesitation, engine does not stall with quick stops, engine does not backfire, and re-verify that carburetor does not leak. It's a good idea to do test drive by driving around town, at highway speeds, and if possible on a long, slow, steep climb.
  4. If problems are experienced, see Problem Solving.
