I’m having and issue with my Johnson wanting to idle or even start under load but once I do get it started it bogs down when I try to accelerate. I’ve done all new fuel line, fuel filters, priming bulb, fuel pump, rebuilt carbs, new gaskets all the way to the crank, new heads and gaskets, coil packs and plugs, and new thermostats. Anyone have any advice?

Looked into issues with seal rings ( crankcase compression ) on the crankshaft ?------Possibly broken crankshaft seal rings.
