Checking the tightness of the carburetor fasteners (Mazda Capella GC)

1. The carburetor is bolted to the intake manifold with four nuts. Over time, the nuts can become loose from vibration and temperature changes, resulting in a vacuum leak.

2. If you suspect a vacuum leak, find a piece of hose that is approximately the same diameter as the fuel supply hose. Start the engine, hold the end of the hose to your ear and run the other end around the base of the carburetor. If a leak exists. You will hear a hissing sound.

3. Remove the air cleaner assembly, marking each disconnectable hose to facilitate subsequent installation.

4. Install the mounting nuts into the base of the carburetor and tighten them securely. The manufacturer does not specify the exact tightening torque for these nuts.

5. Tighten the nuts securely and evenly. Do not overtighten them, as the threads may strip.

6. If, after the nuts are properly tightened, a vacuum leak still exists, remove the carburetor and replace its gasket - see Section 4.

7. Install the air filter and connect all hoses.
