ya you want 32-1 some guys run 40-1 and 50-1. i like 32-1. A little extra oil cant hurt. the bog Most likely would be the main and or pilot im guessing if they had a shop jet it they put a toomey needle in it which they suck i took mine out and put stockers in and havnt looked back. id pull apart your carbs see what size your jets are needle and what clip the needle is on, main, pilot, and how many turns on your airscrew. Then report back with that and elevation and temp.
