Is there a good reason for the brass screws?
In disassembling and cleaning the TB/UIM/LIM, I've encountered several places (TB plates, 5/6 port linkage plates) where annoyingly soft and easy-to-strip-the-heads brass screws were used. Was there any real (engineering) reason for this, or if I can find some should I be fine with replacing them with nice steel hex-head bolts?

Ever since I started working with SU carbs (40 years ago!!??) I've run into the brass screws you refer to.
Either they thought the brass/steel combo wouldn't corrode in the air/fuel environment (optimists) or, when the screw actually did corrode (inevitable, really), it would be easier to somehow remove the softer brass stub.
Either way, they are a pain.
I've taken to replacing the brass with stainless screws, with a liberal coat of anti-seize.
So far, no ill effects.
