Specially developed Long Low-End Needle Conversion Set for 1/8 off-road engines.
The set includes a Long Low-End Needle and matching Mixture Control Needle that directly replace the standard carburetor needles. The updated needle design provides smoother and more linear throttle response, improved drivability, and reduced fuel consumption.
For proper function and optimum performance, both needles must be installed and used together as a complete set.
Direct fit for FX Engines and compatible 1/8 off-road carburetors.
