Neighbor brought over this Honda generator since it would not start. Checked compression and is 60 PSI. Squirted a little oil in spark plug hole and compression increased to 90 - 95 PSI which I think points towards bad rings or scored cylinder. Question is can oil also help seal a valve seat on an over head valve engine?
Accessing the valve cover looks to be a real challenge to even check valve clearance.
TIA
