- If float level is not within specified range, adjust by increasing or decreasing the number or thickness of needle valve shims. Adding or subtracting a shim will change fuel level about 3 times the thickness of the shim.
- Adding shims lowers float level. Shims are available in a set of 3 thicknesses: .012" (0.3 mm), .016" (0.4 mm) and .020" (0.5 mm).
- To install shim, remove the float, needle and needle seat. Check filter for clogging or damage. Install new "O" ring to needle seat. Install shim and filter to needle seat. See Fig 2
. Install assembly into float chamber cover.
- Install seat retainer. Tighten screws firmly. Insert needle into seat. Install float. Recheck float level using procedure in step 1).
