WALBRO WT-997 carburetor

This Walbro WT-997 carburetor can be fitted on any type of motor. The WT997 is certainly one of the most popular carburetors from the big Walbro program because it’s unproblematic to adjust. For this reason it is especially recommended for the less experienced rc-car driver.

When selecting a tuning version, i.e. with bearings and/or a RVS340 steel shaft, the carburetor is also tested under vacuum and optimally adjusted.
