Default Tuning Question

Im having a little bit of a problem getting the tuning on my XTM 24.7 Pro dialed in. Im running Odonnell 30% and a MC-59 plug currently. The fuel is kinda old but it was stored in a cool,dry place with the cap securely tightened. Basically the motor dies if I either let go of the gas or hit the brake. The part I dont get is that it seems to be really rich because it is smoking a ton and spitting unburnt fuel out the pipe but the throttle response is instant. Does this sound like the low end needle is too lean and the high end is too rich? What do you think?

Thanks!

This is actually my third nitro but I have been out of the hobby for about 3 years so Im just a bit rusty on the tuning side of things. So it was broken correctly... no worries there.
