Ray - I really don't like the gasket sealer on the gasket. The reason is no longer valid, as I no longer restore carburetors. I have seen too many carbs come in for restoration that have either been ruined, or at least the restoration cost greatly increased by mis-application of various sealers, including teflon tape. Over time, tiny chunks of the sealer flake off, and find the smallest orifice in the carburetor (normally the idle tube) to clog.
This is just my opinion, and as stated, moot, as I no longer restore carbs.
As to the screws: certainly a solution if you have the tools and the lathe AND the time; but since you have the tools and the lathe, why not just machine new fillister head screws of the correct thread/length? Or, as stated earlier, I do have them available.
I have used a similar technique to re-affix throttle arms to a throttle shaft, where someone loosened the arm on the shaft. I would chuck the shaft in the lathe, drill and tap the end (normally one can use a 10x32 thread), and machined a "screw" from hard brass with a 10x32 thread from a rod the same diameter as the throttle shaft. Using the red loctite you suggested on the thread, re-affix the throttle arm. Once the loctite had set, mill off the protruding "screw head" and "stake" as was done originally. Makes a permanent fix, and if done carefully, impossible to spot on carbs used on show-cars. Generally, not necessary on Chevrolet carbs, as I have new throttle shafts for most of these. But could justify the time on some of the rarer, more expensive carbs.
The two machine tools every enthusiast should add to their Christmas want list is a lathe and a milling/drilling machine.
Jon.
