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 you will need to install a high flow fuel line kit.

Carburettor Specs:

  • Walbro WT-990
  • 15.88mm bore
  • 12.7mm venturi
  • Independent tune-able high and low speed jets

This carburettor does not have an internal choke.

    990 competition modes carby

    Posted by Tom Kelly on 12th Aug 2018

    With this carby fitted there is a obvious increase in response off the mark and the top end sings nice and smooth. I'm not to sure how to word it, but the engine does not seem, like it has more to give like with a standard 990. It is smooth and sounds complete.
