Do you have a purge valve?  If so, you should be shutting down with the 

purge valve, NOT the mixture.  AFP systems don't cut off fuel flow 

completely when you pull the mixture (by design).  Shut down with the purge 

valve and there is no way any significant amount of fuel can continue to 

flow through to the cyls if it's working properly.



If you're shutting down with the purge valve and you're still seeing flow, 

then question/test the purge valve.  New airplane, new tanks...crud could 

have gotten up in there.  Unlikely but possible.



Sniffle valve...only used on horizontal induction sumps afaik.  On your 

vertical setup you shouldn't really need it.
