The EC Blueprinted Two Barrel Racing Carburetor for the Briggs Model 35 and Model 38 Vanguard V-Twin Horizontal Engines is built for high-performance racing lawnmowers. 

From the day it was first built over a decade ago and still today, it’s the carburetor most chased in the Prepared Twin Race Mower Classes. Due to EPA regulations, many late model engines have carburetors that lack the adjustability for blueprinting them into racing carburetors. We use a factory aftermarket two-barrel to build performance while maintaining adjustability for idle and low-speed tuning. 

This carburetor is strictly made for pure racing applications. The carburetor is blueprinted to perform best on the track, not in the pits. The tune of this carburetor is fairly rich at idle, making it unsuitable for recreational hot rods like golf carts, mud motors, etc. 

*Note the idle speed screw is part of the intake adaptor, not the carburetor. This feature is usually only found on horizontal shaft engines. If your intake assembly does not match the one in the pictures, this carburetor may not work for you.
