I did a compression test on my new E-Bay 850 non-runner with my year-old Sears thread-in unit, which replaced one from the Seventies. I got 31 psi on one side, 32 psi on the other with the throttle wide open, half a dozen kicks each side. Valve gear had plausible slack at TDC all around.
I then spent an hour pulling the head, finding fasteners torqued to spec, a tightly sealed head gasket, valves in superb condition and 40-over pistons sucking smoothly through bores with practically brand-new cross-hatching, crowns and milled head dusted with the carbon patina of a perfectly adjusted four-stroke.
A test on my strong-running 50 mpg '72 Combat produced 31 psi on each side, proving yet again there is no fool like an old fool. Has anyone put Sears' return policy to the test recently?
