Make sure the HS screw is 4 1/2 turns out from closed and the LS screw is 12-1/2 turns out. It will run, just be patient.
I followed your suggestion and it turned on once. It felt sort of hot (I don't have the temp gauge) & I shut it off but, upon trying to restart it again it didn't do anything. I double checked the glow plug to check it it was working properly. I'll keep trying.
No need for a temp gage. Once you got it up and running agian...bring it up to temp then shut it down. Get some spit on your finger and then drop the spit onto the cooling head. if it sizzles right off...to hot. If it just kinda makes a little noise at you your pretty good there and if it does nothing your runnin cold. This is the methoid I've used but i am no professional. I have pretty good luck with getting good milage out of an engine.
Dont be scared to lean that sucker out 1/8 a turn until you get it to start and stay running. I was like you when I first got into the nitro scene and didnt want to muck up the engine....trust me their pretty damn tuff. You wont mess it up running it hot a few times. Also when you get it up and running agian just make sure you have a nice trail of smoke coming out the pipe. Smoking coming out...good sign...no smoke..bad.
Make sure that the idle screw is set to where there is a 1/32" to 1/16" opening in the carb when you pull off the air filter and look in there. Should be a picture some where in the manual or go to duratrax.com
good luck...hopefully this made sense.
