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 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 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 consistent as well as a better, more smooth metal finish compared to other diaphragms.
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. Check your carburetor and carburetor listing before ordering.
The .004" Fuel Pump Diaphragm is part of this kit. The thinner .004" diaphragm is the stock diaphragm on 60cc engines or less. Or as a qualifying diaphragm for larger 2-cycle engines. We do not recommend using this diaphragm for main features or heat racings as the advantages and performance are lost after a couple of laps before needing to be replaced. Check your rules 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.
