Overview

In a performance engine bay, this Q-Series carburetor bolts to the manifold flange and meters gasoline against the engine's airflow. The body has a machined finish.

Flow rating is the headline number, and a buyer will need more detail on choke type, fuel inlet and engine fit. The description repeats the title and warranty terms are not given.

Who it's for

An engine builder matching a carb to a large engine can use the flow rating. A first-time buyer or anyone needing a ready-to-run package should look at better documented listings.

Performance notes

A carburetor's flow rating should be matched to engine size and rpm range, since an oversize unit can hurt low-speed response. The listing offers no calibration data.
