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 complete better the rebuild or service performed on your carburetor. 

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 helps identify Tillotson carburetor parts and shows the carburetor's assembly. This helps the D.I.Y. racer to know their carburetor is reassembled correctly. 

Our Pro Kits utilizes our "Fast Action" Main Diaphragm. We made this component 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 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. Check your class rules before ordering. 

This kit includes what we normally call the short gas seat. It's a short seat with a .062" orifice vs. the .093" of the larger alky seat. This type of seat is used almost exclusively for gas engines, especially piston port 2-cycles and small block 4-cycle engines. This is the only difference between the P3-RK and P5-RK. Check your carburetor and carburetor listing before ordering.

The Fulcrum and Inlet Fuel Needle Valve are captured in this kit. Captured is where the fulcrum arm with a fork end "captures" the dowel on the head of the needle. A captured needle keeps the fulcrum arm in contact; this is usually used on smoother tracks.

This kit can rebuild any Standard Volume(Single Stack, Gas) Pump Stack HR Tillotson Carburetor. Due to the age of many of these carburetors, they are commonly modified from their original condition. It is also not uncommon to find these parts will interchange with other carburetors. We make no guarantee that they will fit any other carburetor than the HR single stack carburetors. There is no refund for this part if you attempt to use this kit in any other carburetor. If you do not see your carburetor and are unsure if this kit will work for you, please contact us before ordering.
