Tonight I did some more painting and some more cleaning.  I painted most of the engine parts that needed to be painted MGB red (see pictures below).  Then I did some cleaning.  I started with the intake manifold and the emission control diaphragm (see pictures), which really cleaned up nicely...I'll have to check with a few people to see if they think I should paint it or just leave it the way it is (with a little more polishing in the corners).  Then I started on some carb parts...just a couple of brackets for now.
 

Here's a before/after comparison of the intake manifold.

Here's the after picture...it really came out nice!  It's not quite as shiny as the picture makes it look, but it does look nice.

A before picture of the carbs.

Some painted engine parts...

...more painted engine parts...
