Spec'd compression value Briggs 18hp twin - 422707
I have more detail posted in another thread on my struggles with this motor, but I'm looking for a clear answer on this - what compression value is specified for the 18hp Briggs twins? - this is model 422707.
I went to engine(s) last night and took some compression measurements.
Engine1 (the one I most recently put into the JD 116) - cyl.1 = 50psi, cyl.2 = 75psi.
Engine2 (the spare) - cyl.1 = 65psi, cyl.2 = 70psi
I should have checked this before I installed the engine. What is the expected value for these motors? All these values seem a little low to me.
From reading other threads, verifying that the valves aren't leaking are also key to the compression reading. I'll be checking on that in the near future.
