Default 2nd Gear equals Stall ?

I have an old T-Maxx that has the .15 Pro in it. It was running well but has developed a problem. When I give it full throttle it will excellerate fine until it reaches where the transmission shifts to 2nd and that stalls it. What would cause this?

I put a new glow plug in but get the same results. I messed with the idle control screw a little because it would also lunge when at idle once the engine warms up.
I have my high speed set at 2 3/8 turns... I can't get it figured out today, seems like if I stomp on the trigger it just bogs or floods itself out. That's even holding it up off the ground where it doesn't have a load on the tires.

SET YO OUT FROM CLOSED.ADJUSTING HSN UNTIL WOT RUNS REAL GOOD THEN ADJUSTING LSN BY PINCHING FUEL LINE OFF ABOUT 1 INCH AWAY FROM CARB. MAKE A FEW WOT PASSES THEN PINCH OFF FUEL LINE IF IT RUNS 3 TO 4 SECONDSVIDLES HI N SHUTS OFF UR ALMOST PERFECT..IF IT DOES IT IN 2 SECONDS IT'S TO LEAN RICHEN LSN 1/8 TURN IF IT GOES 4 TO 5 SECONDS REV AND DIES YOUR TO RICH LEAN LSNL 1/8 TURN. WHEN YOU HAVE THEM TWO RIGHT SET IDLE SO WITH WHEELS OFF GROUND TURN IDLE SCREW UNTIL WHEELS STOPP TURNING...WITH THOSE SETTINGS IF IT STALLS GOIN TO 2ND U MIGHT WANT TO OPEN TRANS. AND SEE WHY..
HOPE THIS HELPS..
ALSO IT'S NOT EASY OR FAST TO TUNE A NITRO ENGINEUR NEEDLES BACK TO FACTORY HSN 4 TURNS OUT FROM CLOSED SET LSN 1 1/2 TO 1 3/4

Thanks I'll try that.. Pretty sure the smaller .15 motor tuning specs calls for 2 1/2 turns on the HSN, but I'll look again

PS.. Those caps mess with my eyes when trying to decipher your message
