Just resurrected a 10HP Johnson. On first start up noticed where the paint was already discolored was blistering hot. Is this normal for this model. Engine runs and pumps well. New impeller etc. Did not pull the head to inspect yet. Does this have something to do with the baffle, or possibly I need a new gasket under the head?
Also what would cause gas to come up and spill out of the plunger, when under pressure, on the 1956 tank that came with it?
