I AM CURRENTLY RUNNING A SIRIO TX-18 ON MY T-MAXX. THE ENGINE SEEMS TO BE RUNNING ALOT HOTTER THAN THE FACTORY RECOMMENDS. (220) MINE SEEMS TO RUN MORE AROUND THE 250-290 RANGE, EVERY TIME I TRY TO RICHEN THE HSN OR THE LSN THE TRUCK WILL HARDLY RUN. THESE ARE THE ONLY TEMPS I HAVE BEEN ABLE TO GET THE TRUCK TO RUN HOW IT SHOULD. I HAVE TRIED TRINITY MONS 20% AND TRAXXAS 20% AND HAVE HAD THE SAME RESULTS. I HAVE ALSO TRIED O.S. STANDARD AND #8 GLOW PLUGS W/ SAME RESULTS. OUTSIDE TEMP IS ONLY AROUND 50 DEG. CAN SOMEONE WITH THIS ENGINE LET ME KNOW WHAT HSN AND LSN SETTING THEY ARE HAVING THE BEST LUCK WITH AND THE TEMPS THEY ARE RUNNING??? I AM OPEN TO ANY SUGGESTIONS!!! THANKS
 
DO YOU KNOW WHAT BASE SETTINGS ARE? THEY ARE JUST THAT BASE SETTINGS, NOT THE END ALL DO ALL BUT A GOOD PLACE TO START. A COUPLE OF THINGS THAT MAKE A ENGINE RUN HOT, DIRT ON THE CASE AND FINS. DIRTY AIR FILTER. SOMETIMES ENGINES GET THAT HOT RUNNING IN GRASS AND DOING A LOT OF HILL CLIMBS. START WITH THESE SETINGS:

HIGHSPEEDNEEDLE 5.5
LOWSPEEDNEEDLE 2.5 GENERALLY FLUSH WITH THE END OF THE SLIDE.

YOU MIGHT WANT TO BOOKMARK THIS WWW.TEAMTRINITY.COM THEY HAVE THESE SETTINGS AND THAT'S WHERE I FOUND THEM FOR YOU. PLEASE DO NOT POST IS CAPS AS IT IS RUDE ON THE INTERNET AS IT IS PERCEIVED AS SHOUTING. GOOD LUCK WITH YOUR ENIGNE.


PS I HAD THE BEST LUCK WITH THE MCCOY MC59.

I'm guessing you guys are on cell-phones?? haha

BTW you may have an air leak..try RTv'ingthe back plate and the carb neck.
 
Mine ran the same. Over 280 when pushed hard. Are you running wide open on long straights. I did and the temps would hit just under 300. Do check for an air leak. High temp silicon sealer will take care of it one if it exists.
