    cleaning & rebuilding an Edelbrock 1406

    This carb is not yet 5 years old. Hasn't had more than 3000 miles put on it. At 12 mpg x a 13 gallon tank, that's 156 miles per tank or less than 20 full tanks of fuel.

    Hesitation at light throttle. Been doing that a while. Checked for vacuum leaks, adjusted it, etc. Just seemed like I couldn't get rid of it. So I decided to order a rebuild kit and tear it apart for cleaning.

    Talk about crud...geez. Today's gas leaves a lot to be desired...

    All done and back on the wagon. Runs a whole lot better now.

    Added a stainless 3/8 fuel line (from the stock fuel pump to the carb) and an AN filter.
    Never did like that rubber hose and cheap off the shelf hose clamp-filter I put on when I first rebuilt this engine, but I was out of time and money back then, so I got it running.

    Will post a pick of the top of the engine soon. I also got the alternator/AC brackets powder coated. Engine looks al whole lot better now.

    I am not sure the problem is "today's gas" as much as it is the car doesn't get driven much. 600 miles per year means the car sits a lot and the volatiles in the gas evaporate leaving the varnishes that you see. If you drove the car as a daily driver, you probably wouldn't see that. Letting cars sit is really bad on them in many ways.

    It’s a Phenix Industries filter, with 6an male fittings on each end. It can be disassembled and cleaned on occasion. The screen is 40 micron stainless mesh.
    I happened to get this at a local independent auto parts store, but you can get them thru Summit Racing and others as well.

    And here’s a look at the front of the engine, with the Bills Hot Rod brackets powder coated flat black. IMG_1169.jpg
    these must have been 20+ years old, made from Stainless steel, but rusted after polishing them up a few years ago. Guess the stainless doesn’t really last forever...

    There are many grades of stainless, and some are more corrosion resistant than others. The more nickel and chromium, the better the corrosion resistance. 316 stainless is austenitic as is 304, with 316 being more corrosion resistant. Both are not ferromagnetic. Some other stainless steels of the 400 series (used on a lot of cheaper exhaust systems) are ferritic and they are ferromagnetic and don't resist corrosion very well.

    So stainless steel can corrode, especially the cheaper kind.

    Wow, that rusted like everyday steel, powder coating sure made a difference.
