Failure Analysis Of Automobile Exhaust Holes

Fault inspection and troubleshooting: According to the above phenomenon, the cause of the muffler firing was carefully analyzed. In order to find the crux of the fault, the ignition sequence, the spring force of the distributor's power-off contact arm, the ignition timing, the spark plug, etc. were not found. Continue to check the carburetor air filter and valve clearance to no avail. I started the engine again and it worked normally, but it didn't take long for the old disease to recur.

Stop and check the distributor part again. After disassembly and careful inspection of the car vent, it was finally found that the copper glue wire from the breaker contact arm to the low-voltage terminal was broken at the corner, leaving only a few thin copper wires connected. After replacing the broken copper wire, the malfunction disappeared.
