Will this carburetor kit fit my ATV model?

The kit is built for 4-stroke small-displacement ATVs and lists compatibility across many popular Chinese brands and model families. Confirm fit by checking engine size (50cc–125cc) and throttle handlebar diameter (7/8" / 22 mm).

• Compatible engine sizes: 50cc, 70cc, 90cc, 110cc, 125cc 4-stroke engines.
• Known brand compatibility: TaoTao, Coolster, Venom, Kazuma, Baja, Loncin, Vitacci, SunL and similar models.
• Handlebar fit: thumb controller and grips designed for 7/8" (22 mm) bars.
• Check included intake manifold and mounting pattern against your frame before installation.

How does the PZ20 compare to other carburetor sizes?

The PZ20 sits between the smaller PZ19 and larger PZ22 in throttle body size, offering a compromise between peak power and fuel efficiency. It typically gives better top-end airflow than PZ19 while being more economical than PZ22, making it a useful all-rounder for most recreational riders.

• More airflow than PZ19 — improved responsiveness at mid-to-high RPMs.
• Better fuel economy than PZ22 — sensible for daily or trail riding.
• Comes pre-jetted and with essential seals to ease setup and reduce tuning time.

What components come in the FVRITO kit and why are they useful?

This package bundles the carburetor with every common wear and connection piece so you can install it without chasing parts. That makes it a time-saving repair solution and reduces the risk of compatibility gaps when upgrading an aging fuel system.

• PZ20 carburetor with jets, float and choke components for immediate use.
• 35 mm air filter and intake manifold to match the carburetor and seal to the engine.
• Thumb controller, accelerator cable (46.5" / 1180 mm), 7/8" grips and inline petcock for full throttle control and fuel shutoff.
• Spare spark plug, fuel line, fuel filters, gaskets, O-ring and mounting screws to complete installation.

How difficult is installation and what should I expect during setup?

For someone with basic mechanical skills and common hand tools, installation is straightforward: remove the old carburetor, mount the intake manifold and carb, hook up fuel and throttle cable, then set idle and test. Some tuning of air/fuel mixture and idle speed may be required for optimal performance on your specific ATV.

• Requires simple hand tools and basic mechanical familiarity with ATVs.
• Throttle cable length (46.5" / 1180 mm) fits most standard frames; may need minor routing adjustments.
• Expect short test rides and minor jet/idle adjustments for best running condition.
