I'm not using my M3W every day so it often rests for one or two weeks in the garage.
Today I had a morning tour and suffered strong petrol smell for several minutes while driving but could not find a leak or something unusual.
Starting the engine was unusually fast (only few rotations till the engine fired) and I had strong pertol smell afterwards in the garage and for several miles in the cockpit on the go.
Any proposals where I should search for the reason of the unusual smell?
(The garage floor was dry, no leakage there either) Fuel tank is filled 50%
