Re: Compression Interpretation

Since I just went through this stuff with mine here is what the book says.

In order to properly read compression you must turn the engine over six times. If you build compression within the first two or three strokes it is OK, if it takes all six to build good compression you have bad rings. If you build no, low or mid compression every stroke you have a bad valve/head gasket/etc.

Yours is Oh Tay, good.
