How to Check Small Engine Compression?

step 1
If there is a screwdriver on the small engine, unscrew and remove the cylinder head to access the spark plug.

Step 2
Slide the flat blade tip of the screwdriver under the edge of the rubber sleeve. Gently swing the rubber sleeve on the spark plug.

Step 3
Place the socket wrench on the spark plug. Use a wrench to loosen the spark plug and pull it out of the engine. Set the choke to the off or closed position.

Step 4
Practice three to four times on the starter rope to remove any fuel remaining in the cylinder or crankcase.

Step 5
Insert the hose of the compression meter into the empty spark plug hole. Pull the starter rope 10 to 15 times or until the compressor needle reaches its maximum level. Compression should reach at least 90 PSI if it is hot and at least 100 PSI if it is cold.
