Angle Gauge Adjustment Tool
Manufacturer recommends that some carburetor adjustments be performed using Choke Valve Angle Gauge (J 26701). While preparations and actual adjustment may vary with each individual adjustment, the procedure for using the angle gauge to check the choke valve angle remains the same. Use the following procedure to perform adjustments requiring the use of the choke valve angle gauge.
- With choke valve closed, place angle gauge magnet squarely on choke valve. Rotate degree scale on angle gauge so that zero degree mark is opposite pointer.
- Rotate leveling bubble on angle gauge until it is centered. Rotate degree scale until specified degree mark is opposite pointer.
- Place gauge on throttle blade as specified in carburetor adjustment procedures. If bubble is centered, adjustment is correct. If not, adjust carburetor as outlined.
