A carburetor that leaks fuel, has worn throttle-shaft bushings, or cannot be adjusted to idle consistently may need rebuilding or replacement. This 4MV-style unit is a potential option when the original manifold, choke arrangement, linkage and calibration match.

- manifold-operated choke arrangement
- vehicle-specific jetting and linkage must be checked
Replaces / Cross-References
- 4MV
Common Reasons for Replacement
Hard starting, erratic idle, fuel seepage, hesitation or worn throttle components.
Fitment Notes
Match the stamped carburetor identification number, choke linkage, fuel-inlet position, throttle bracket and intake mounting pattern. A matching model name alone does not establish correct calibration.
