Here, Nick from VireEngines.com demonstrates how to test each step of the fuel mix going through the vire 12 engine, and talking about the problems that can occur at each stage. The vire 6 & 7 models use a carburettor with inbuilt pump, otherwise the same. near the end of the video, the engine is running and you can see the typical amount of water pulising out of the wet exhaust. be careful to note how to avoid flooding your engine.
