Choosing the Right Carburetor Size
For 70cc setups (from Sport to Racing), the 24mm PWK is highly recommended and performs exceptionally well in most cases.

For 50cc engines, smaller PWK carburetors are more suitable.

For 70cc–80cc high-end setups, a 28mm PWK delivers optimal performance.

For 80cc–100cc engines, the 30mm to 34mm PWK models are ideal.
