I have a Honda Harmony HRB215 K4 SDA that won't pull start but if I take off the recoil and drill start it, it runs perfect?

I have a Honda Harmony HRB215 K4 SDA that won't pull start but if I take off the recoil and drill start it, it runs perfect. I did a compressin test, the pull start only gets the mower to 60psi but the drill gets the mower to 150psi. This mower does have a decompression vale where the ehaust opest about 1/8 of the way. I tore the ead off and checked and cleaned the valves. They don't stick open. Could there be an issue with the decompression valve? Or would it be the piston rings?
