[AT] 430V update

[Gunnells, Brad R]

Last few carbs I’ve done I soaked in a plastic bowl filled with Simple Green. It’s also a good cleaning agent and is biodegradable. I also used it as a piston soak when I was rebuilding some 2.4 liter Camry engines in cars I bought with stripped head bolt holes. Those aluminum pistons looked like new when they were done.

    I have had very good luck using this carburetor cleaner and it costs less
    than anything found in the Auto Parts Store. I use it at full strength ....
    Pine-Sol All-Purpose Cleaner, Lemon, 144 oz, Bottle which costs less than
    $9.00 a bottle.  I have yet to have it fail other than when passages need to
    be drilled out.  And if that is the situation, no carburetor cleaner is
    going to work. The first time I used it I was very dubious but I was
    completely surprised.  Try it... you too may be pleasantly surprised.

    The old timers swear by boiling carbs, using something acidic instead of
    water if there is rust.   Lemon juice definitely works but requires a rinse
    boil to get the sugars off of it.  Preferably two rinse boils.   So it's
    time consuming.
    
    If rust isn't a problem I just dip them in my  NAPA carb dip.   If it is I
    will dip them per normal(430V carb is in the can now) and then do the boil
    after getting as much carb dip reside off as I can.
    
    One thing I have noticed by boiling. You know that thin, fine grained
    scale/sediment that is like concrete in the bottom of the bowl that the dip
    never really gets out? Boiling will get that.

    > The carb rebuild has started.   I was clearly right in that somebody has
    been in the carburetor recently. There's a rebuild kit in it, but a couple
    of important components were not replaced. The throttle bushing was old and
    probably was a little looser than I had thought. One jet was not seated all
    of the way, and the float clearly is not adjusted correctly.  Also the water
    leak that froze the cylinder also put some water in the carburetor.  So
    there was some rust in two passages, partially clogging  them.

    localized and minor so we'll see after I soak it and hand twist a drill bit
    in the passages.   I fortunately have drill bits the exact correct size.
