Bulent,
   Are your injectors the Cosmo original or new ones ?? If the original ones
there is the possibility that they are leaking down from residual fuel pressure
of the system after shutdown.......Leaky injectors are common problem with
high mileage rotarys and cause flooded starts.......In my RX7 I provided a
.020 oriface between pressure line and return line to bleed pressure to the
tank on shutdown.......This has also been suggested to purge a vaporlock
or air from fuel lines after running a tank dry.......Our fuel pumps have excess
capacity and the small pressure loss from the oriface is easily accomadated..
FWIW

On Saturday I drained about a quart of oil since I had overfilled the oil pan. Noticed that the oil smelled of gasoline. I wander if someone else had the same experience and what it could be causing it? Buly

Hi Buly,
 
Mine has always done that, as did my RX-7, so I'd say it's normal.  How mush is too much would be a good question though.
