Thank you guys!!!!! I pretty much have the same problem. Runs really rich in the mid range. So rich in fact that the motor runs real hot. Lean on top and bottom and to make things worse, The mixure changes drasticly from full to empty tank. I put a pump on it and that help big time. I would like to get ride of the pump cuse its heavy and its harder to prime the motor for the first flight of the day.

I have a satio .40 and it runs PERFECT !!!!!!!!!!!!!!!!!

Love that motor. Wish my 72 ran as good.

I will check tomarrow on the spray bar on the 72. (cross my fingers ) I will let you know how it goes.

Again, thank you!
