Thread: fuel and oil leaks

When I took delivery of my plane I had to fly it from Western Canada to Eastern Canada. After one day of flight I parked it for the night and did not shut the fuel valve. The next morning there was a pool of fuel under the plane. That has been going on each tiime I forgot to shut the valve.At least one gallon would leak overnight I finally discovered that this fuel (which makes de cabin smell fuel in flight) comes from right under the air filter where there is a little plastic support that acts as a cup, and goes there from the air tube that runs from the port carburator to the air filter. Did anyone have that problem and a fix for it.

Yesterday after a one hour flight, I noticed much more black spots (oily) that went from the exhaust onto the floats. Nothing abnormal in the flight nor around the engine that I can notice. Is oil running out of the exhaust a sign of troubles to come ?

Sounds like you need to adjust the float arm in the carb bowl. They are not shuting off the fuel. That will also cause other issues like you are experiencing.

I looked in all the bokks and manual provided by Rotax and flight design and do not see how to adjust the float arm ? Any suggestion ?

You need to pick up a Bing carb manual. FD has nothing about the details of the Bing. The manual is about $10 and thin.
You can call me if you would like and we can talk about it, but eventually you will need the carb manual.
