After 20 years of 2CV racing, the 21st season in 2010 was a step into the unknown! Notable technical changes meant that it was impossible to predict who would be up at the front, as a new control tyre and the opportunity to run a Weber carburettor were introduced to level the playing field. But whilst the new Toyo tyres were universally accepted, the Weber carb proved a bit more controversial! Was it better to stick with the original Solex, or switch to the Weber, which was believed to be more powerful? Despite all the testing and number crunching, it was a surprise to many as to how the races panned out!
