I had the car back to the dealer numerous times. They changed the leverage on the carb and installed many factory sponsored "fixes" but neither VW or the factory had a fix. I learned to live with it but it was sure a pain. Other wise I liked the car and drove it to 80,000 miles. The problem, I am sure was the single carb design and / or, manifolding of the fuel feed.<< I've read that this was a problem from the beginning, thanks for confirming it with your actual experience. I've driven single carb Type 3s for 14 years and I've never been able to completely eliminate the flat spot. It's especially pronounced if you accelerate while cornering (something that some early Type 3 reviews made note of). VW made many modifications to the carb, especially within the first two years, most of which I believe were attempts to solve the problem. Somewhere in the workshop manual there's a section that suggests some further alterations that can be made to the accelerator pump to minimize the flat spot if all else fails.
