WALBRO WT-990

Now available with the stainless steel 340 steel carburetor shaft with tuning lever ZN0078/02 This Walbro WT-990 is a high efficiency carburetor which may be fitted without problems on any type of motor, (a must for tuned engines). The original carburetors can give bottom acceleration problems. Since the fuel supply is just below the venturi the air/fuel mixes very well.

In this carburetor are both needles, (low and high), more separated from each other so that they do not affect each other so much. Due to the absence of a choke valve and axle 20% more air can goes through. Standard used on the Zenoah G240, G270 and G290.
