What you need to know is, there is a certain "flow" direction of cooling air inside that generator housing. Yes, air is drawn up, into the bottom front. It starts it's cooling process by cooling the rotor and stator. From there, it travels through the radiator. From there, it's forced through the radiator due to the fact that the center "bulk head" is sealed against the top panel of the generator. That air has no choice but, to go through the radiator.
From there, it's channeled around both mufflers, and, finally, it is jettisoned out the bottom towards the rear. So, yes, to get proper cooling, the top panel "MUST" be in place for the channeling of the air to be effective. Hope this helps. By the way, was there any corrosion around the actual sensor tip?

I ran mine with the top off one time and it heated up and shut down.
Lesson learned.
