nibbi PZ19 Carburetor Kit with 35mm Double-Foam Air Filter for 50–125cc — Replaceable Jets, Cable Choke

This Nibbi kit combines a PZ19 carburetor and a washable, double-layer foam 35mm air filter to suit a wide range of small-displacement dirt bikes, pit bikes, ATVs, scooters and go-karts.

The kit comes with extra main and pilot jets so you can tune mixture and idle settings for varying altitudes, fuel types, and riding conditions.

How does this carburetor improve engine response?

The PZ19 body and replaceable jets let you fine-tune the air/fuel mixture to recover lost throttle snap and smooth idle. Replacing an old, clogged carb with a properly sized PZ19 often eliminates bogging and hesitation when accelerating.

• PZ19 intake diameter: 19mm (0.75").
• Main jet shipped: #75; included extras: #70, #72, #78 for tuning.
• Pilot jet supplied: #35 plus extra #32 to refine idle mixture.
• Cable-style choke for simple cold-start operation and adjustments.

Will the 35mm air filter keep dirt out on off-road rides?

The Nibbi air filter uses a double-layer foam construction that traps larger and finer particles while still allowing adequate airflow. It's washable and reusable, so maintenance is straightforward after dusty or muddy outings.

• Double-foam layers for staged filtration and longer service intervals.
• Washable with soap and water, then re-oil per foam filter practice.
• Designed to match the 35mm intake for correct sealing and airflow balance.
• Helps protect the engine from abrasive particles that accelerate wear.

How easy is installation and routine maintenance?

Installation is straightforward for anyone comfortable with basic carburetor work: remove the old carb, bolt the new unit in place, connect throttle and fuel, and set idle and mixture. Routine upkeep mainly involves cleaning or replacing the foam filter and checking jets for clogs.

• Cable choke and basic adjustments make tuning accessible without special tools.
