Picture is blurry but it appears to say "no good" for the front rotor. It might still work fine, but start planning for what you'll do when it starts having hot start problems.

If I am able to read the blurry image correctly, your compression is VERY low. Also, your engine crank speed is poor. Consider a new starter and battery along with a engine rebuild.
