• Fuel lines (from fuel tank to filter to pump to filter to carburetor). See Fuel Lines on page 14-27.
• Exhaust system (for restrictions). See Section 15 – Exhaust System.
If the carburetor floods or leaks fuel at the float bowl gasket or carburetor vent tube, the fuel inlet valve could
be worn or dirty. Another cause of this condition may be a damaged float that has filled with fuel and sinks.
For elevations above 3000 feet, main jets other than standard operate more effectively. The following chart
lists the elevation ratings for various jet sizes. No adjustment is required for the pilot jet. If the vehicle idles
roughly, turn the pilot air screw (Figure 14-3, Page 14-3) out until the vehicle idles smoothly.

When removing the carburetor body, the throttle return spring (11) must be disconnected. Note its
proper orientation so that it can be replaced with the same orientation.
The carburetor must be kept upright during removal.
