We designed our kits using OE parts or equivalent to superior aftermarket components. Our aftermarket components prioritize racing condition durability and performance over cost and price margins of other aftermarket parts.
Our kits also include additional components to better complete the service performed on your carburetor. In these kits we included the fuel strainer screen and the cork gasket where the OE Tillotson kits and even many of the aftermarket kits do not include.
We also include a parts diagram without Pro kits something no other OE or Aftermarket kits include. That has parts break down a list that help identify Tillotson carburetor parts as well as shows the carburetors assembly. This helps the D.I.Y. racer to know their carburetor is reassembled correctly.
Our Pro Kits utilizes our “Fast Action” Main Diaphragm. This component is one that we made in the aftermarket as a performance upgrade over OE and other aftermarket metering diaphragms. This main metering diaphragm has improved response and reaction over standard metering diaphragms. The “wagon wheel” features a more consistent dowel height in the center making the fulcrum height adjustment for consistent as well as a better, more smooth metal finish compared to other diaphragms.
This kit uses the 0.040” High Volume Fuel Pump Diaphragm Gasket. This allows more volume to be pumped by the diaphragm. This is often a tech item in kart racing.
The P2-DG differs from the P1-DG with the thinner .004” fuel pump diaphragm. The .004” diaphragm is used primarily on engines less than 60cc but is also used as a qualifying diaphragm for engines larger than 60cc. The thinner diaphragm can pull harder and respond quicker at the expense of longevity on engines bigger than 60cc. Check your rules and carburetor before ordering.
