Thanks for all the replies. I am believing that it all comes down to
an old worn engine. The manual I found states 31-42 psi at idle, so
at 15 psi I am pretty low. 59-71 psi at speed. Not quite as low
there. I am hoping to be able to get at the oil pump with out pulling
the motor. Now, if the rain would just stop I could get to work.
cheers all,
Kurt
