Tom; I think your compression numbers are way low. Even cold you should see 145 psi or more. Hot compression should be 180+ psi. Since plugs are out a simple test might be to get a helper and some chopsticks then with chopstick on top of piston mark chopstick at TDC then roll engine by hand and get BDC measurement all cylinders. Then compare to each cylinder.
