Based on that, I would NOT fly the aircraft UNTIL I had
personally inspected it to see what was leaking and from
where. If the float valve was leaking, the fuel level would
rise and over-flow from the vent on the carb. That is an
easy fix. If a fuel line is leaking, it is also an easy
fix. If a crack is in the float bowl, you replace the carb,
also easy but more expensive.

What is the history of the airplane before and on the last
flight? Was is parked with the fuel valves OFF or ON?

engine bay.
|
| How many of you would / would not fly this aircraft based
on the above info?
|
| (I appreciate that more info would be nice, but it's all I
have available).
|
| Many thanks,
