Re: [DML] running rich??

[Martin Gutkowski <webmaster@xxxx>]

Your metering head plunger may have got stuck. Usually only happenns 
with cars that have sat for ages, but definitely worth checking. With 
the air box removed (engine off) you should be able to push the flap 
down and feel the weight of the plunger on it (it works like a see-saw). 
It goes up as fast as the flap is pushed down but does not drop back 
down as fast. There will be quite a lot of resistance if the car has 
recently been fired up.

Otherwise my next guess would be the CPR as you suggest, however they 
usually run over-lean when they fail making starting bad but getting 
better as the car warms up.
