How to Open the OHC Cover of a Honda Lawn Mower

Regular maintenance to your Honda lawn mower such as oil changes, cleaning the air filter and changing the spark plug helps to keep your mower running at peak efficiency. Normally it is not necessary to perform any major work, especially on th OHC models. Occasionally, though, you might find it necessary to adjust the valve clearance on an older unit. Adjusting the valves is not a major task, but does require some disassembly of the mower. Opening the OHC cover of a Honda mower includes removing the top cover to access the upper securing bolts of the valve cover.

Slowly lift the cover off the engine, and allow it to recoil against the handle bar. The starter rope recoil will keep the cover out of your way.
