The E.C. Pro Gasket Kits are exclusively constructed for professionals in the small engine racing world. 

We designed our kits using O.E. 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 O.E. 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 O.E. 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 and a better, more smooth metal finish than 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. 

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 needle's head. A captured needle keeps the fulcrum arm in contact; this is usually preferred on rougher tracks and if the carburetor orientation is with the fuel pump stack facing downward.
