Carb Sheild + WBW Choke Cup Combo — AB / Pro-K

Carb Protector + WBW Choke Cup Combo — AB / Pro-K

Choose your preferred carb protector and pair it with a matching WBW Choke Cup for a complete, convenient setup.

Select an AB Carb Shield or Pro-K flame arrester, then choose the size or model that fits your application. Each combo includes the corresponding choke cup—no guessing which cup to order.

The WBW Choke Cup covers the intake during washdown and helps with priming during stubborn starts or after jetting changes. Remove the cup before running the engine.

Available options

– AB Carb Shield: Flexible, 3D-printed TPU construction with no metal mesh. Available in low-profile 1.5″ and standard 2.5″ heights; fits standard aftermarket carb adapters.
– Pro-K Flame Arrester: Select the model and size suited to your carburetor setup. Includes the matching WBW Choke Cup.

Each combo includes

– One selected AB Carb Shield or Pro-K flame arrester
– One matching WBW Choke Cup

Sold per carburetor. Order two combos for a dual-carb setup. Verify adapter fitment and available clearance before ordering. Carb adapters are not included. AB Carb Shield worm-gear clamps are not included.

AB Carb Shields are for competition use only and are not USCG-approved flame arrestors. Refer to the selected Pro-K model’s specifications for application and approval information.
