Late 60s Carburetor Heater Box Front Attachment?

This may be a dumb question, but was the carburetor heat box supposed to be attached with anything more than the 2 machine screws at the carb's entrance? I think at one time we had a sheet metal screw in the front. Not saying it was right. Attached is a picture of the front.

2 screws on carb entrance, and one in the area photo. I've also seen them on the top of the airbox going into the recoil shroud, may or may not be factory.

Are the ones in the front just attached to the sheet metal?

The side one in the pic was a sheet metal screw. Dad's '67 had lost that many decades ago.

IIRC the Late 1960's Airens had a sheet metal screw in the front and 2 small machine screws that went into an air intake flange mounted on the carb. Some people added a sheet metal screw to the top to prevent rattling. On the Airens one would remove the heat shield and reattach the machine screws ( really tight) and attache an an air filter element with a sheet metal cover to two outer ears on the flange. This allowed the Tecumseh motor to cool for Summer work. There were attachments like a rotary lawn mower, a sweeping brush and a chipper shedder, and probably more. IIRC alot of folks did not read the manual and ran the tractor year round with the carb heater shroud on. Lots of thrown rods. I often wonder if this contributed to Tecumseh's mixed reputation.

Sheet metal screw makes sense.
Round head or hex head?

Steve I saw in an old Tecumseh repair manual that the air filter could be installed. My impression is they were only recommened for use with the heat shield off. yes?
