I have an IO-360, with a forward facing RSA-5 fuel servo (90 degree bend from airflow performance).  After doing a few initial runs, I'm getting significant fuel pooling/coming out of the front of the fuel servo on shut down (1,000 rpm) using the Idle cut-off.  I've had it tested and it's not the diaphragm.  Has anyone else experienced this?

 

Thanks

Doug
