I reinstalled the head cover and temporary gasket, filled the machine with oil, and fired the thing up. Thanks again ShotOut, for all of your help.
Any ideas and guidance would be greatly appreciated. It sounds like there is metal to metal contact so the intake valve appears to be seating. I wonder what might cause the strange lash readings. But there is huge clearance between the intake valve stem end and the rocker arm of 0.040". Finger over the plug hole indicates compression is now there. I sprayed carb cleaner on the stem and the valve immediately began to move freely. I suppose I left gasoline in the engine and it got stale. Valve stem covered with goo that looked like typical gasoline varnish. Discovered the intake valve was not moving freely. Good spark, but discovered zero compression. I am uncomfortable simply setting the lash to spec and putting the machine back together, and would appreciate guidance.īackground: I bought a new Karcher pressure washer equipped with the GCV160 engine.

With all these new EPA rules and state regulations, they set the motors to run so lean they run like crap. The Briggs and Strattons now a days arent so reliable as they use to.
