PWK type Carburettor d=19mm with powerjet Barikit

Carburettor 19 PWK type from the manufacturer Barikit. Model with Powerjet, starter with lever.

Barikit brings us this carburettor for small modifications with Power Jet System
The Power Jet system provides extra petrol at high revs, based on a small jet that is responsible for injecting this extra petrol as if it were a turbo.
The power jet system is simple but ingenious. It is a duct that goes from the carburettor bowl (the part of the carburettor where petrol is stored) to the carburettor inlet, that is, to the air suction area of the carburettor.

The more revolutions the engine reaches, the more air enters the carburettor, which generates a strong vacuum inside the power jet circuit that causes a small amount of petrol from the bowl to rise through the duct to the carburettor air inlet. This mixture of air + petrol enters the engine atomised and provides extra performance at high revs, increasing top speed, response, and power.

By adjusting this small jet, we can also control at how many revolutions we want the power jet to come into action.
