14.5HP OHV B&S engine compression
I have an old Yard Machine that has a 14.5HP B&S engine
in it. I was mowing the other day and without making any
noise or smoking, the engine suddenly quit and lost com-
pression. Is the problem most likely a blown head gasket
or a broken valve spring or a flywheel to shaft key that has
sheared? Any input would be greatly appreciated and for
your help I will say "Thank You" beforehand.
