Re: Vaccuu gave test location

A steady reading of 18 inches of vacuum is quite acceptable. While the gauge is still installed it's the best way to set your carburetor idle mixtures and you might gain a bit more by doing so. With the gauge installed, adjust to maximum vacuum and then turn back in (lean) until it just begins to drop, then back to the maximum again with the screws out no further than needed.

Rust flakes in the fuel pump sediment bowl isn't at all uncommon. If it's made of metal and is itself beginning to rust you might consider some sort of gasoline-resistant coating on the inner surface after cleaning it. I believe they were originally plated to prevent rusting.
