Zenith Power Jet Valve Assembly J1022

Zenith Power Jet Valve Assembly – Enrichment Valve for Select Zenith Carburetors

This power jet valve assembly is used in select Zenith carburetors to provide additional fuel enrichment under load. When engine demand increases, the power jet valve opens to supplement the main circuit, preventing lean conditions that can cause hesitation, loss of power, or engine damage.

A failed, stuck, or leaking power jet valve will often result in poor acceleration, flat spots, lean surge, or inconsistent performance. Replacing the valve assembly restores proper enrichment and correct fuel delivery when it matters most.

Features & Benefits

• Restores proper fuel enrichment under load

• Precision-machined for correct operation and fit

• Brass construction for durability and fuel resistance

When to Replace the Power Jet Valve

Replace the power jet valve assembly if you experience:

• Hesitation or stumble under acceleration

• Lean running under load

• Poor power despite correct main jet sizing

• Evidence of internal fuel leakage or sticking

This component is often overlooked during rebuilds but plays a major role in real-world performance.

Bottom Line

If your Zenith carburetor uses a power jet system, this valve assembly is not optional—it’s essential. Correct enrichment equals better drivability, safer air-fuel ratios, and proper engine performance.
