Reviews of WEBER parts For Business

That's a Pierburg carb, I had trouble with mine, but the adjustment screws were shot so I swapped to a Weber 32/36 and am much happier now.

Also might be an idea to remove the round plate under the back seat and extract the fuel guage sender to see if there is any crud in the tank. If it's any consolation, a new filler neck is alot cheaper than a Weber, but you really ought to fit a weber anyway as they are vastly superior to the standard carb!

My 1989 Scirocco GT had exactly the same problem. It's the Pierburg carb that is giving you grief. In fact my Mk2 Jetta did the same. Get a replacement Weber fitted and the fault will be cured. I did this to my GT and the performance was amazing. As a bonus the fuel economy was noticably improved.
