Info needed,
I have a McCulloch Mac140 that is leaking pressure from the oil pump while performing a pressure/vac test, I know this is a plunger style pump operated by a crankcase pulse like the fuel pump but am unsure if there should be a pressure leak from the pump.
I would think this would cause a lean run condition.
Is there suppose to be any pressure leakage thorough the oil pump?
