The EC Pro Gasket kits are exclusively constructed for professionals in the small engine racing world.
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 a parts break-down 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 also uses the .020” Fuel Pump Diaphragm Gasket. This gasket is the standard or stock gasket for Tillotson carburetors. The .020 fuel pump gasket holds less volume and many times required by kart class rules. It is highly recommended racers use the P1-DG kit if rules allow on all carburetors that require .006 Fuel Pump Diaphragm but allow the high volume .040” Fuel Pump Gasket.
