Excellent material...research before install
Good material. Holds up well if you have a brand new engine and never opened the valve cover. Else get some permatex, the center of valve cover may be warped from muffler heat and over torque. The four screw pattern design is not ideal (it leaked without permatex after a 2 hour run with cover right side up; cleaned all surfaces to metal with none scratch pad and WD40, elevate front end of tires 3" to keep spec oil in compartment, carb cleaner on cloth to clean surfaces, used thin tack of permatex engine side with gasket, then generous bead on upside down cover (used the side that was not exposed to muffler; did not want to chance wasting my last gasket). Torqued cover and clean excess. No leaks, no white smoke, and fuel breather and engine runs great.

Release mechanism woes...
The first start after rebuild was without issue. Shutting off the hot oiled motor presented issues with the release mechanism not functioning. New oil, gaskets, balanced shaft throughout, good condition and clean housing throughout. A cool engine starts everytime (spring composition maybe???). This Briggs & Stratton brand has it's issues with the release mechanism. Have to oil up the compartment, then clean the closure area, manually prime the sump, and change the oil after ~10 hours run time. The release mech is a very bad design; either material or profile spec. My motor runs great after start up, however, I can tell that the release mech is sticking in place after a long motor run with immediate restart. Have to manually teeter the flywheel with hot motor shut off to get the release into position. 'model 31' valves@0.004in; 0.006out. Picture is of the replaced cam.
