Motor Tuning Problem - Almost dies after WOT

[iDrift10]

Well before the colder weather my Revo was running perfect. However, now that the temp has dropped 30 degrees I'm having a little issue. I know that when the temp drops you should richen the HSN because of the denser air. My Revo was running a little warm (280-300) so I richened the HSN to get the temps down. Now that the temps are in a respectable range I'm having a issue after wide open throttle. From take off all the way through the power band the engine runs perfect; nice trail of smoke, nice performance, nice temps. However as soon as I let off the gas after a high speed run the car drops to a idle that is barely running then after a few seconds or if I tap the gas the idle returns to a perfectly fine healthy idle. If I lean the HSN back up to get rid of the almost dying issue the car over heats. Ran a few tanks trying to trouble shoot it and I just can't figure it out. Thanks in advance for any help.

Side Note: Running a Picco 26 Red Dot.

It's sounds like you may need to idle the engine up. Turn your idle screw clockwise about 1/8 of a turn

also might be a tad rich on the bottom,

I think it's still too lean, sounds like you are tuning for temps and not performance. Wrap the cyl head in any weather that's cooler than 50°f and richen the needle until you know it's too rich, then tune it back to good performance. If that doesn't help the stalling problem try leaning the lsn just a wee bit.
