It removes the shellac from the fuel and the carbon deposits - you
sometimes get back-fires into the carb.

Don't think the OP mentioned the vehicle make and model, but I'm pretty
sure it's not a Model T Ford...

Hi, I didn't mention it in the very first post but I thought I did say
later on that it's a Citroen C3. I've just looked in the Haynes book
and that says the egr valve is buried at the back of the engine.
Great;(

I've seen some vacuum gauges on ebay so I'll get one of those to
connect to the egr valve and see what it says. Is there anywhere else
I should measure the vacuum?

Where do I need to spray the carb cleaner? Just in the egr pipe?

Thanks again.

I don't think Model T's had an EGR.

Indeed. I also doubt that a vehicle with an egr has a carb...
