I have an OS 60FSR inverted in a plane and the only way I can get it
to start is to turn the plane upside down. The engine constantly
floods. The fuel lines are level with the carb per the specs in the AC
manual and there is no way to lower the tank short of tearing the
Front end off the bird. Anyone have any ideas?

Try a Cline regulator?

Haven't done that myself. But I don't see any other way to
slow the flow down if you've got the tank too high.

Get a pair of hemostats and clamp the supply line until you are ready to
start the engine. Flip it through a few times before unclamping the supply
line. Make sure you are not too rich.
