Metering lever gauge

This gauge is a "must have" because it makes setting the metering lever height FAST and EASY.

Southwest Airports makes this custom gauge that is similar to the official Walbro gauge but has the correct dimensions for the *button-type* diaphragm found in nearly all WG repair kits sold in North America and the EU.  For details on the differences in the gauges, see the carburetor tune up page.

The gauge is stamped on one side with "" so as not to be confused with the official Walbro gauge and all of the clone gauges (photo above is not of the actual lettering on the gauge).

Use of the custom gauge will save time, trouble, and expense for all pilots who service the Walbro WG or WB  carburetors.  Fortunately, the WB repair kits come with the height of the ML set correctly but, even so, the ML height should always be checked because the ML lever can be accidentally bent in handling.
