Re: Running again

Hello Andrew,
    Usualy when you lay up your car, the fuel should be treated with a
stabilizer to keep it from gumming and blocking up the small passages in
the carbs.  Sounds like your carbs are gummed up, which will require
some type of spray solvent and fuel system cleaner additive agent to
flush things out, or maybe even dissassembly.  Problem is that ZS carbs
do not have convenient places to spray carb cleaner for all the spots
that get gummed up, but the bowls come off nicely once the carbs are
off.  So, I'd try the easiest first...drain out the old fuel, change the
fuel filter, add some fuel system additive, pop off the top of the carbs
and spray down any little orafice you come across, pull the dampers and
spray cleaner down the metering jet hole, and put things together.
Check the timing, gap the plugs and points, take it for a spin to heat
things up and get the additive circulating.  If this does not fix
things, then it is a teardown and solvent cleaning of the carbs in my
opinion.

Some other possibilities are that the dampers, although new before
retiring, have holes in them caused by something in the fuel that
attacks rubber components.

The black soot is definately an over rich condition if it is dry or
dries when you pull the plug, black soot that is oily and does not dry
is usually chunky and wet appearance from oil fouling, not smooth and
dry like fuel soot.

In my humble opinion, yours for speculalation.

Glenn  Merrell
