A carburetor is an ATV or go-karts engine's lungs, and quality parts like these ensure a better ride. Our PZ20 carburetor with 20 mm Intake for 50cc, 70cc, 90cc, and 110cc ATVs and go-karts features a left-side mounted manual choke lever. The mounting hole spacing is 1-15/16" (48 mm) center to center with 3/16" (5 mm) through holes.

Do I need a PZ19, a PZ20, or a PZ22 carburetor?
If you are bewildered by the carburetor choices you are not alone. The PZ19, PZ20, and PZ22 carbs are very similar; including a 48 mm mounting hole spacing. The only real difference is in the diameter of the engine-side intake; the PZ19 uses a 19 mm opening, the PZ20 has a 20 mm opening, while the PZ22's engine-side measures a nominal 22 mm. All three carburetors can be used on engines from 50cc up to 125cc.

So which is right for your machine? In general, the PZ19 is more common on 50cc, 70cc, and 90cc engines as these require a bit less power that their larger cousins. The PZ22 is a better choice if your engine is in the 110cc to 125cc class simply because it takes a larger dose of the gas/air mix to run the larger engine at peak performance. Although the PZ22 provides a bit more power, it comes at the cost of greater fuel consumption. The PZ20 is the happy medium of the trio; better performance than the PZ19 but with better fuel economy than the PZ22.
