Air screw is on the front of the carb. We used to run the same setup and i had to go to a 110 main. Check for air leaks around the exhaust flange. We had a lot of problems with the Hotseat pipe and found the weld around the flange was cracked. Go up on your main and but a box of plugs and keep checking the plug. Dont let it run lean for very long or you will be redoing the top end. If I remember right the air screw should be 1 1/2 turns. What kind of oil are you using? Usually 32:1 works good.
