Product Details

Key Features

Requires the use of special "notched" float to achieve proper clearance and to operate properly. Notched float number 116-11 Or Kit with float and extensions 116-10.

An improved jet extension design that actually screws into the metering block. The main metering jet then threads into the end of the extension. The installation effectively moves the fuel entry point for the main jet out into the fuel bowl. In this location it cannot be uncovered by fuel, causing a lean condition, during periods of hard acceleration or braking. 2/Pkg.
