The TF-1A-6U is a drop-in replacement for the following applications:
- Our TPP-4500DF-A gasoline generators
- Most other generators and vertical engines that have an offset mounting pattern (see the picture below)
The TF-1A-6U uses our new TillotsonTCT fuel system technology to provide a substantial upgrade in performance to standard carburetors. It is our semi-universal configuration that can be used on gasoline-only engines. It is packaged with a variety of swap-able throttle and choke levers to fit a variety of applications (see photo). It can be used to replace Ruixing, Jingke, Huayi, Kinzo and Wisdom carburetors used on Chinese brand 5.5 – 6.5 (160-212 cc) engines commonly used on generators (Champion, Generac, and others), and Toro, MTD and other lawnmowers. Check the bolt pattern and choke levers show in the pictures below for compatibility.
Why switch to the TillotsonTCT? The TillotsonTCT is a patented new fuel system technology designed to lower emissions and fuel consumption while improving acceleration and performance. It is ideal for use on older engines that do not meet current EPA standards. Additional benefits and features include:
- Easy start
- More stable power, even under load
- Superior acceleration compared to the standard carburetor
- Quieter tone
- Multi-lever packaging to fit both vertical and horizontal engines with manual chokes and a spring choke option for MTD engines (included)
- Built-in dual fuel capability (gasoline and propane)

Compare your carburetor to the pictures below for compatibility. Check the direction and distance of the mounting bolt from the engine side of the carburetor (see chart below). Note that the air bleed and channel on the face of your carburetor may be on the opposite side as on the TillotsonTCT (see picture). That is ok; the TillotsonTCT will still be compatible. The TillotsonTCT does not fit Briggs & Stratton and some vertical Honda carburetors with a “side by side” bolt pattern. The TillotsonTCT also does not have a fuel cock like on some Honda carburetors. The fuel cock is not necessary on the TillotsonTCT, but if you desire one, you can add an in-line fuel valve.
This version is fully adjustable and may not be used on engines certified under EPA III standards. Our EPA III version will be released in the Spring of 2017.
