I have tried to improve on this idea and hope it's okay with Prof'. In the picture, maybe the gen is set to far to the rear?

My present enclosure is constructed using 1x2's for framing, 30" long, 24" wide and 20" high. Using what is available at Home Depot, the black 4x8 sheet of 'QuietBoard' ~ 'SoundStop' board is coming soon. Now comes the fun. Trying to stop the heat recirculation from the hot engine air blowing out over the genhead and muffler that enters the genhead. Using Prof's idea of the coffee can, this idea has worked. Use the coffee can, leaving the outer end in place and cutting a slit 1 1/2" wide by 4" up one side, turn the can, 110 degrees to the left for air intake. This helped with the problem of hot air recirculation into the genhead. Lining the can with carpet will help lower noise. Air intake for the engine was baffled by using the quietboard.
Testing continues with using a top and no additional fan. This is questionable but with leaving the muffler end open it works. Will get the meter out soon and also test the 3'x 4' rubber one side, carpet the other side DUR-A-BULL mat from Lowe's.

You are doing fine, Floyd. Anything you want to improve. Yes, the gen in the photo is a little too far back. Have you looked at my totally amateur video of the gen in a cardboard enclosure? The link is posted a few back. On that one the gen is forward and I make a comment that it should be there for proper cooling. As long as exhaust does not get back into the box the genny seems to do fine heat wise. I would be extremely cautions on a really hot day with constant AC use. Maybe allow the box to be elevated a few inches off the ground - like with scrap 2x4 blocks so air can get in and out. Also wonder about a 8" hole in the top over the recoil starter as being something that would help cooling without compromising sound reduction. Shucks - just the sides without the top would make a difference.

Keep experimenting!
