lol measure the temp of the tool box. man i hate temp guns just me. good for some bad for the new guys. set yer lsn flush or leave it a lone if oyu never touched it from the box. turn the hsn all the in. NOT TIGHT STOP WHEN YOU FELL IT GET TO THE BOTTOM. now from the bottom turn it out 4.5 - 5 turns out and start her up. will it start/ idle by itself? no then turn hsn in 1/8 turn (lean). repeat until it will idle. you should be in the ball park @4.5 turns. now notice any spitting out the exhaust, alot of smoke when you apply the throttle, or engine dieing? yes lean it 1/8 turn. what you are shooting for is smoke heavy too rich. mild smoke is good truck will run but not up to max potential. light smoke yer right there. and where i like mine is light smoke just noticeable, i run mine right there just before it starts pop and spudder. from i have read the trx2.5r runz hotter then normal.

hate to see what the temp is but hey i ran my first gen tmaxx (.15trx)like that for hell 7-8 gallons before it quit.

now once you get her running then take temps with the gun. but you gotta get it running first
