With the price of Amal Premier Concentric carbs going up, we have started to source (and use) these new Wassell Evolution carbs

Wassell Evolution carbs are the same as Amal Premier carbs but made by "Wassell". In fact, Wassell Evolution carbs use the same pilot jet, main jet, floats, and many other parts as the Amal Premier carb.... so yes they are pretty much the same carb as the Premier at a fraction of the cost. Plus, they are easier to obtain.

We have many Wassell Evolution bore sizes to choose from. Single carb applications where typically fitted to the T100C, TR6, A65T, B25, C25, T100 and other various Triumph and BSA models. All carbs ship free here in the USA.
