    you needa common pressure meter that fits your spark plug holes …

    remove the sparkplugs,
    install the short hose of the meter
    crank the engine over 4-5 times and check compression value
    release the air pressure by pressing the purge valve on the meter repeat for second plug hole

    compare readings… should be within 10% or so and above 75-80 psi each

    utube is your friend…
