That’s easy. Remove the spark plugs and stick a screwdriver in one of the holes. Maintain contact with the piston as you slowly rotate the flywheel by hand (don’t push on the screwdriver). Rotate till the piston is about half way down on its downstroke. then stop turning. Now give a push on the screwdriver. Any clunk or movement represents the amount of looseness in the wrist pin.
Repeat with other plston.
