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

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.
