JET Model 4150 Stage 2 carburetors, based on popular Holley double-pumper carbs, have all the same modifications as the 4150 Stage 1, plus inspected, blueprinted, and calibrated fuel metering circuits to match modifications done to the engine. Also, the air horn is milled to improve and equalize airflow between the primaries and secondaries. Electric chokes and four-corner idle circuits are optional on all Stage 2 carburetors.
