When EC Carburetors designed the first PK-1 carburetor, we made it comply with the box stock rules while anticipating the potential of stock appearing carburetors. 

By the time the second version of the PK carburetor, the PK-1B, the Tillotson carburetor had become the most popular body for stock appearing engine and carburetor builders. 

Over the last few years, we have been so busy developing Tillotson products and components to forcefully make time to develop our version of the stock appearing carburetors. Starting with the original CAD for the PK Tillotson Carburetors, we could map out our machining to clear and shape as much of the body as possible without using any epoxy. Using state-of-the-art CNC equipment, we can consistently and repeatedly machine each body to maximize results. 

To overcome an already competitive market, we designed a new stainless butterfly and shaft to fit our new shape. Looking at the induction system as a complete unit, we designed our exclusive new air filter adaptor that reduces turbulence and helps the laminar flow. We also CNC ported and matched the plastic insulator to the stock intake port to complete the induction system.
