Walbro WT-257 high-performance butterfly carburetor. 2 jets (independent high and low), 15.88mm bore, 12.7mm venturi. Internally metered for higher fuel flow than the WT-603 / WT-668 / WT-643/4/5. Features single fuel fitting (no primer bulb and no return fitting). 

This carburetor is an EXCELLENT upgrade for many RC airplane, helicopter, car/buggy, and marine applications. Works well on most Zenoah engines and clones. Substantially outperforms stock carburetors.

Requires one throttle linkage arm for RC use, HPI15468.

This carburetor does not have a choke, so we recommend purchasing a velocity stack with a built-in choke.
