I would be happy to take a look at anyones car for a quick poke and diagnosis. If results are expected, a small fee may apply, but nothing you can't afford.
Peps: That pump you are talking about is a accelerator pump, yes, to enrichen the mixture when you mash the pedal to the metal. And every carbie has one of some sort, just with the 2TG you have 4 squirters, one for each cylinder! You would have a big flat spot without it. If your carbies are going out of tune, there must be something wrong with your linkages. With good linkages that are not loose or anything (I use the factory set up), they should only get out of tune if the weather changes.
