[Spridgets] Weber Help

[Robert E. Shlafer]

You can squirt a bit of carb cleaner on the throttle shaft bearings and see if the idle changes which will help diagnose worn shaft bearings.

Also check for contamination within the idle jets and at the bottom of the fuel bowl as minute stuff will get by the carb's. mesh filter and clog the idle jet's tiny ports far more so than the larger ports of emulsion
tubes and main/air corrector jets.

Really minute stuff such as corrosion from the fuel tank/system will also get by even the best of fuel filters but you'll see this
(brown 'sludge') at the bottom of the fuel bowl if this is the case, though this minute stuff normally begins clogging the tiny progression holes as well eventually leading of off-idle roughness on initial gently acceleration as well as uneven or
less than stable idle.

It must be a really old and well used carb for that to happen.  A good  
weber specialist ought to be able to do this for you.  There is a book  about 
Webers _www.veloce.co.uk_ (http://www.veloce.co.uk)  that shows  how to do 
this for yourself.

My winter project is to correct  this problem.

It looks like the ball bearings in the throttle shaft  need to be replaced.
