Hi fellow Europa experts,
I have about 1.7 hours on my 914 engine and have had it up to 4,000 rpm so
far. I just discovered today that the starboard carburetor has leaked some
fuel into the catch bowl that sits underneath. I have the hose connected to
that bowl and it has evidence of fuel.
Does anyone have an idea of what might cause this? It can't be normal. I have
a fuel pressure gauge in the line out of the fuel pumps and with the engine
shut down and one electric fuel pump on, I get about 4.8 psi. With the second
pump also on, the pressure rises to about 6.3 psi. The pressure regulator is
supposed to keep the fuel at 3.5 psi above airbox pressure. Then the engine
is not running, the airbox pressure should be atmospheric and I would expect
the fuel pressure to read 3.5 psi with one or two pumps running. The engine
is under warranty, so I will probably have to contact Rotax.
Any ideas?
Thanks,
Dave Anderson
