Default SH .18 stock needle settings

I met someone who has a RedCat Tornado.He is new to "the hobby", and brought it by my house because he could not get it started.

Some imortant notes:
1. Car is new. He said he started it once and it "went crazy", meaning he obviously hit is hand on the throttle servo arm and opened it wide up (that's common problem with this design).
2. The engine seems okay. It turns over fine (I was worried about his con rod) -it just won't start.
3. I put the heat gun on it - that allowed it to turn over for a split second, then it dies.
4. The glow plug was fried.A little odd for a new one, but I understand metal shavings during break-in can do this. I put a new glow plug on it - an O.S. #6 - nada.
5. I asked him if he "messed with the needles" and he said he has - quite a bit.Ugh.The LSN looked flush and the HSN looked about 1.5 in ffrom flush. I think this is what it could be,and if not want to at leastrule it out.
6.I also noticed the air filter was off. He noted they had been trying to start it with the air filter off to see inside of the carb (go easy - we were all new at one time). I put my Exceed Forza air filter on it.
6. I checked everything else out (prime, carp opening, etc. etc. etc.) My next step is to take the engine apart and check out what's going on - but after I rule out the needle settings.

I looked at the engine and saw 18 on one side, and SH on the other so need to know the needle settings for it. Additionally, can anyone think of and issue that would prevent an engine from evenstarting ifit wentWOT fora few secondon it during its first start.? The inner components felt and sounded okay. I understand he might have lost some performance, but it should at least start.

Is this a RTR with a pullstart? A troublesome engine with a pullstart is one ofthe most frustrating situations around. If you have a starterbox, rearrange the pegs and use it. Once all the bugs are found, engine broken in, tuned reasonably well, he can go back to the pullstart.

No starter box unfortunately. I imagine it is just completely out of tune (as he just started turning the needles and tried to start by trial and error). He's bringing it by tonight and if I can't start it after setting back to stock, I'll have him leave it with me and take apart the engine to see if there is anything I can determine. It has a good pinch and as noted "feels" fine when I turn it over. I'll post back what I find out (I'm adamant about starting it!). ;-)
