Need some help here. I have never had a engine want to quit on the down lines. The set up is a Tartan Twin on gas. (I know I will call Jim Cline when home). When flying any average to long down line the engine just dies, as the plane rotates back to level flight it restarts. (you can hear the ignition cutting off and then back on). All lines are o.k. with great draw, vent line is clear. However when tipped toward nose fuel runs out of the vent line. I am thinking maybe it is causing a suction problem when the fuel shifts forward.
Any suggestions?
