Okay, with that oil mix, you should have no problems. I always cringe when I see people mixing 100:1, but to each his own. Your mix at 32:1 sounds fine to me.

Try the tuning method. It usually works. Takes about 30 or 45 minutes to get it all dialed in. The constant starting and stopping gets old, but once you're finished tuning it, forget about it. Fly it.

You will notice your starting becomes a bit more work with the bottom end leaner. Usually a nice wet choke helps. If it bothers you, richen the low speed needle a tiny bit and deal with a burble at low throttle settings. That should clear out your mid range burble and then it would only burble at very low throttle positions.
