Specs At A Glance

Good To Know

Q: Does this carburetor need a fuel pressure regulator? A: Most carburetors in this class run best with fuel pressure held around 5 to 7 PSI, so a regulator is a good idea if your pump output is higher than that.

Q: Is an electric choke wiring kit required? A: Yes, the electric choke needs a switched 12V source that is live with the ignition on, and a proper connection ensures consistent cold-start enrichment.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
