tuning in benchmark fcr41

So i picked up a fcr41 carb that was setup for a mild 686. I am putting it on my stock 660 running a exhaust tip and cover off the intake box. I run it at 4500-8000ft elevation.
Anybody running the fcr know what jets i should start with or where to set the clip at?
thanks Clint
