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 ÄË›€ÅƒÅ¡Fast ActionÄË›€ÅƒÅ› 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 ÄË›€ÅƒÅ¡wagon wheelÄË›€ÅƒÅ› 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 0.040ÄË›€ÅƒÅ› 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 .062ÄË›€ÅƒÅ› orifice vs the .093ÄË›€ÅƒÅ› 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 uncaptured in this kit. The uncaptured fulcrum arm is without a forked tab instead the end rests on top of the needle. The uncaptured needle does not have a dowel for the arm to ÄË›€ÅƒÅ¡captureÄË›€ÅƒÅ›. This traditional has been used on smoother racing surfaces but is very common for any kart racing engines.
