Important Safety Note: Always wear eye protection to prevent injury from escaping gas or flying particles. It is recommended that this procedure be performed by a qualified mechanic in a properly equipped shop.
Testing Procedure Highlights:
- Ensure cylinder, head, reed cage, intake manifold, and spark plug are installed and torqued correctly. Remove exhaust pipe and carburetor.
- Seal exhaust ports using appropriate rubber expansion plugs or metal plates.
- Insert the correct carburetor adaptor into the intake manifold.
- Pump air pressure into the engine to 6 PSI. Never exceed 8 PSI.
- If pressure is lost, use soapy water to locate leaks and repair as needed. A leakage rate of 1 PSI per minute is acceptable; lower rates yield better performance.
- Listen for leaks at various points, including crankcase seals and power valve areas.
