Small Engines (Lawn Mowers, etc.): Honda push mower compression., arinet, valve rocker

Question
I've got a honda push mower with a GXV140 engine on it.  I measure the compression to be around 50 PSI but I read that some of the other engines honda makes have a compression lowering device.  Does this one?  How do I disable it to get the right compression reading?

Answer
Hello Steve:

You can View a Breakdown/IPL of the Mower/Engine at this Site Addy, http://hayward.arinet.com/scripts/EmpartISAPI.dll?MF&app=ASP&lang=EN&TF=Mainfram... and Select the Catalog American Honda. Select the Engine File. Then Scroll Down to your Engine and Select it. I Used the First GXV140 Engine in the List for Reference. Loosen the Exhaust Valve Rocker Arm so it Just Barely Moves when you Turn the Engine. The Compression Release is on the cam and Opens the Exhaust Valve a Small Amount Just Prior to TDC to Assist in Starting. The Compression should be No Less than 80psi. Usually any Compression Below 80psi will Cause Problems with the Engine Idle. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
