Holley's new Truck Avenger is the first 4-barrel carburetor designed from the ground up for off-road performance. this pretty much floods out a 2 stroke engine. I have a 2011 grubee skyhawk gt5 angel fire slant head 66cc with a cns carburetor the down tube or leak tube on my carburetor is spitting out gas i can understand a drip but its like draining out i've taken it apart looked at it all floats are good jets are clean and needle valve is fine it just seems like the gas is constantly running into the carb also they sent me a clutch cable that binds. Disconnecting the gas line allows the engine to start and run until the excess gas is used and reconnecting the gas line used to result in normal fuel. Pull the fuel pump fuse when you suspect the carbs are about to flood (this will most likely be in stop-and-go traffic). Stromberg identified it as their Model EE-1. The basic Holley carburetor four-barrel family includes the smaller 4150 and 4160 series and the larger, 4500 series, commonly known as the Dominator.
