RTE WT-990 Competition Mod Carburettor

* NEW * We have changed the bearing arrangement to a double seal and a locking mechanism.  Four (4) heavy duty stainless steel bearings are installed and locked to the shaft via o-rings.  This centralises the shaft and stops any axial movement.  It also stops high speed throttle closed vacuum leaks, which are the leading cause of seizures on highly tuned engines.

The Competition Mod carburettor is the new addition to the Rooster Tail Engines modified carburettor series.

Bridging the gap between the Bearing Mod and the Full Mod carburettors, the new Competition Mod will perform exceptionally well, and fit right at home on the smaller engines.

As with all of our modified carburettors this one includes high quality, stainless steel sealed bearings on each side of the throttle shaft to help support and seal this area from dust ingress in the most demanding applications.

When this material enters the shaft bore area on a normal carburettor, it can cause excessive wear on both the shaft and the internal bore of the carburettor body.

This mod stops 99% of dust and sand from entering the carburettor bore and the engine, thus making it more reliable and saving you from an expensive engine rebuild from dust and sand ingress.

The Competition Mod carburettor also includes a lower pop-off pressure, with an increased closing pressure for faster response.  Also the fuel flow is increased and the venturi signal strength has been raised for a boost to overall performance.

We recommend you install our RTE High Temp Carburettor Gasket and RTE High Temp Velocity Stack Gasket for superior heat protection.

Due to the extra fuel flow required it is recommended you install our RTE Super Flow Fuel Line Kit.
