If glazing occurs then compression is compromised and combustion gasses travel around the piston rings, often referred to as blow by, and into the crankcase. INVERTER GENERATORS. Ahh. Sounds good. I believe the screw you are talking about is adjacent to where the clear rubber tube enters the bottom of the carb assembly (float bowl). This is a hose that travels from the valve cover of the generator’s engine either down the side of the block where it vents or it may be routed to the engine’s air intake manifold or filter, where normal crankcase gasses are consumed and burned by the engine. Featured Products. If insufficient BMEP is present during break-in, i.e., the generator is lightly loaded for its first 50–100 hours, the cylinder walls will glaze or develop a polished appearance. This should be varied periodically, which normally happens as air conditioning or heating units switch on and off thermostatically.
