Engine quit due to valve guide sliding out causing rocker arm to be immovable resulting in bent push rods.
Clean engine with a Gunk type product. Remove valve cover. Loosen bolts and remove old cylinder head. One bolt is located inside valve cover area. Remove old gasket and inspect and clean that surface. Attach new head with new gasket using existing bolts. Torque to 18'#s with a cross type pattern. Attach new rocker arms and push rods. Set valve clearance to .004 - .006. Attach valve cover with gasket. Check oil level. Start and let it warm up. Let cool remove cover then check valve clearance again. Replace cover.

Stopped running. Turned to be a bent intake push rod and broken rocker arm
Removed head. Replaced both rocker arms, intake pus rod, push rod guide exhaust and head gaskets. Torqued head in 3 stages to 216 in/lbs. gapped intake to .004 and exhaust to .006 at TDC

Added oil and gas. Now running great

If you need to replace push rods use steel (exhaust) they are the same length

Gas leaking from tube breather
First I opened the top of the mower to expose the housing cover. Secondly I removed the four housing bolts to remove the housing cover from the mower. Next I removed the tube breather and installed the new tube breather and replaced the housing cover with the four bolts previously removed and closed the top of the mower. I filled the mower with gas to check for leaks which weren't any leaks. I proceeded to mow the lawn with ease.
