Thanks guys for all the tips on refinishing my throttle plate. I tried a number of products on it and it still maintained the dull gray finish. Here's what it looked like before:
I found best way to clean it up was the simplest. First I dunked it in a Simple Green solution and scrubbed it to get all the loose stuff, and greases and waxes from the other products I put on it. Then dryed it with a terry cloth towel. Then I buffed it with a blue nylok wheel in a drill mounted in a vise. Then I cleaned out all the little crevices with Brasso and Q-Tips and buffed it again. Thank heavens I came home with 600 Q-Tips from Golden Gate, I was wondering what they were for.
Here's how it came out (and below):
Once I cleaned it up I noticed an interesting thing. The stamping of the carb number looks like a restamp. Oh no! But if you look closely at the stamping you'll see 3810 stamped twice. Once faintly and then above it more deeply, like someone missed the first time, and then got it right with the second shot:
Another thing I noticed is the quality of the aluminum and machining of the original vs a new replacement throttle plate I was going to put on this carb.
The original thottle metal has a more silvery look and probably has some different alloys mixed it the aluminum. It almost looks like a dense pot metal with almost zero casting flaws. The replacement metal look more like a light gray aluminum you see today with lots of little casting flaws. Probably too many Coors cans in it.
So I'm going to reuse the original and probably throw out the replacement.
Still having fun!
