    ive aquired another one of these, and plan on learning how to repair it. ive
    got the owners manual, but not the service manual (gonna order one friday if
    i can find one). question is this: the carb in this car has been cleaned and
    repaired using 2 existing carbs already. the gas tank has been
    'sandblasted'. i should mention that the car did sit for ~4 years with the
    fuel in it. stabalizer was added, but i doubt it was enough. the car gets a
    spark, kicks on for ~5 minutes, then dies. takes ~10-20 minutes to get it
    running again, then it dies (so i dont break anything, i havent turned it on
    since then). friends have suggested replacing the fuel pump, spark plugs and
    wires, cleaning the intake, and possibly checking the piston rings. also,
    the compression was low, but it was built up using tranny fluid. i should
    say ive had a mechanic working on it, and he's the one who's been telling me
    all this. he agrees with all of what my friends said and that it would take
    work to get it going. already, the air filter, spark plugs, and fuel filter
    have been changed. the old fuel was flushed and new fuel is in there. i plan
    on changing the oil again. am i missing something here? i should mention
    that when the car is on, it idles rough. not BAD, but rough. any thoughts
    and/or suggestions greatly appreciated. also, im a newbie when it comes to
    mechanics, so please be thorough with your explanations. thanks abunch guys
    :)

    What exactly are you referring to? The outside of the tank or the inside?
    Low compression could be caused by many things. You should check the
    mechanical timing to make sure that it's correct. But it sounds like your
    rings might be just a bit sticky since a wet compression test showed an
    improvement. What were the actual wet/dry compression numbers?

    Your symptoms could also be consistent with a vacuum leak. Check all of the
    vacuum hoses around the carburetor. You may need to use a flashlight and a
    small mirror to facilitate your inspection. Another common source for a
    vacuum leak on these units is the carburetor base. This is the large
    rubberized block underneath the carburetor. Start up the car and then spray
    some carb cleaner around the base of the rubber block where it mates with
    the intake manifold. Make sure that you spray around all sides of the
    rubber block and keep the air cleaner on to avoid a false positive reading.
    If a vacuum leak is present, then there should be an rpm increase when you
    spray with carb cleaner.

    In addition, there should be site glasses on the side of the carburetor to
    check the float levels. The fuel should be at the black dots in the middle
    of the site glasses.

    both just to be safe. the mechanic said it had something inside called
    'varnish' from sitting so long. thing is, few other people i talked with
    said you could add 'HEET" and clear out any water and possibly varnish in
    the gas tank. would the gas tank need replacing if it sat with fuel for so
    long?
    ill see if i can get that later today. the mechanic is working right now.
    the

    friend i was just speaking with said the same thing, cept that the carb was
    put back on twice by the same person... so i dont think (i hope) its a leak.
    ty for this info. i will put it to good use and report back.

    ps - assuming i needed to replace a lot of parts, does anyone have an
    estimate? ty again!

    You may need a new mechanic! Sandblasting the inside of a gas tank is
    likely one of the wackiest things I've heard of yet. I would've gone for a
    solvent approach as it would minimize the risk of leaving any grit behind
    which could plug up and/or damage your carburetor or fuel pump.
    That's all the more reason to suspect a possible vacuum leak. The person
    doing this work may have overlooked something. In addition, when vacuum
    hoses get old they become brittle and are fairly easy to break if they're
    not treated with care when removing them.

    I just bought my son the same car but his is the Si with fuel
    injection. Had new CV joints, new tires, new paint. It had a problem
    with overheating. I changed the thermostat, fan switch (which
    wouldn't work at all) and finally the radiator cap which was leaking
    out a little bit of coolant and getting hot every other time he drove
    it.
    The wierd thing is it just had a clutch job. Now the gearshift adn
    clutch have a slight vibration to them at lower speeds.... whenever
    you put it into a higher gear the vibration starts again until the
    RPMs get above 1500. It almost sounds like a tooth missing from the
    drive shaft connnecting the flywheel/pressure plate to the
    transmission.
    This car is SO much fun to drive though. I've bought both Chilton and
    Haynes manuals. Each has their own strong points. Chiltons is more
    the factory points and Haynes is the do-it-yourselfer. I'd love to
    get a Factory manual but the price can be steep.
    Good luck on your project. It sounds like you need to redo the whole
    fuel system....pump, filters, lines. Pull off the line where ever
    you have the most slack and look at the fitting. If you see something
    which would make your cardiologist
    cringe,,,,placque,,,,grunge,,,,,replace the whole fuel lines. I
    restored a 68 Fastback and had the same problem....It was the crud
    breaking off the lines as the bounced and clogging up and blocking
    fuel flow.....
    Good luck.

    If you know where you're going
    Well, there you are.
