Our all-new TillotsonTCT TF-2A-6U can be used in open Honda GX160-200 and “clone” class racing, where the rules permit use of any carburetor (for classes that require standard carburetors, use our PK-1A).  The TF-2A-6U fits directly onto Honda GX160-200cc and most clone engines without needing an adapter.  This model is calibrated to the stock engine, but can be adjusted for tuned engines through its idle circuit and its AFR (Air-Fuel Ratio) screw or by a simple jet change. The TillotsonTCT offers substantial benefits over conventional carburetors, including optimized air-fuel ratio and better fuel atomization, which result in improved acceleration, faster lap times,  and lower fuel consumption and emissions.

The TillotsonTCT is also an ideal upgrade for both indoor and outdoor commercial tracks.   The reduced fuel consumption helps reduce operating costs, and we can calibrate the TillotsonTCT to reduce CO emissions by more than 40% without losing performance, for safer indoor operation.



Here’s what some of our customers are saying:

South Africa, June 2016: 

“Our tame go kart guy won every heat and the final in Capetown on  Saturday, very much influenced by the performance of the TillotsonTCT, to the extent that his competitors were all complaining”.

Brazil, December 2016:

“[T]here was an improvement in time with the new carburetor.”

“[E]ngine responses improved and this is very important in the race result.”

“I am very pleased with the result of the new carburetor, some friends have been interested in this carburetor TCT.”
