Re: Accelerator pump dribble

[Chris Wright <Christopher.Wright@Sun.COM>]

<x-flowed>If there is a dribble from the pump jets after the pedals released, it 
is likely to be in the return springs in the pumps or stiff diaphragms 
as they rely on those springs to reset against the actuating lever.   
I'd have thought it was unlikely that partially blocked jets were 
causing a build up of pressure which oozes out afterwards, because the 
tube that goes down into the float chamber is not sealed against the 
top, so any pressure is likely to just drip back into the float chamber, 
not dribble out of the jets.
