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

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.
