hi ken
warm the engine up,
remove the 4 spark plugs, place the plugs back in the boots
and rest the plugs on the engine, i do this for 2 reasons, mainly it prevents
stuffing up the coil and to see how strong the spark is.
hold the throttle wide open
and crank about 4 - 5 times
your looking 4 consitency, from memory around 148psi is stock.
