If I had a 520 Continental and wanted to run a carburetor I would run the main one the O-540 Lycoming uses. MA 4-5 10-4404. But that's just me.
Compromise is failure on the installment plan.

personally I don't even like to run a little lean , so if it appears to be running lean and your mixture is set all the way rich on the carb you mite want to consider having it tweeted or completely overhauled , you mite check with speedwheelie (Jeffords airboats) if you decide to go that route or Schmitt aviation (Tom Schmitt)
