Re: [doc] fuel distributer

Hi Martin
   
  I will try and explain the symtoms a bit more clearly...
   
  In first or second gear driving at around 10 to 15 mph the car is fine - no lag no smoke.  When you get fast enough to get into third gear and you put your foot down you can feel the car hesitating and thats when it makes a low audible humming noise and then after a delay of about 10 seconds it picks up speed.  This will happen if the car has not been driven in a few weeks and only happens for about the first 10 minutes the car is driven, if you drive the car everyday the symtoms never arise.  I had the feeling that there was some gunge still in the old fuel lines and in the metering head that was blocking fuel from getting to the engine and by blasting the throttle it was clearing the gunge and this was making the smoke - I know for a fact that the car is not rich as he passed the emmisions test in his mot about 3 weeks ago with fllying colours.
   
  I dont think the car is in any way faulty but to know that his metering head/engine is not about to blow up would help us a great deal!!!!

  Hi Mat

Fuel distributors rarely go bad and whatever you do, don't take it to 
pieces and try doing it yourself. They are very delicate, but extremely 
simple inside and there's not a lot you can just clean.

I sounds like it's running very rich if you're getting black smoke, and 
hesitation under accelleration can be an awful lot of things from the 
advance bob-weights in the ignition distributor to the lambda system, to 
the control pressure regulator - and I've once had a metering head where 
the plunger was too tight and wouldn't move freely. It's tough to say 
for sure.

I have a known good secondhand metering head on the shelf. A refurbished 
one, through us is around £300.
