Default Did I damage the engine in break-in?

Hi everyone. This is my very first post on the forum.

I Just bought a HPI Bullet yesterday (my first Nitro car ever, so I am a complete newbie),but have had some HUGE problems getting started with it ever since.
I was about to write here earlier today because of a problem I had, but just tried "one more time" before i posted, and then all of a sudden it worked

With that said, im still having some issues, and even worse, after some reading got scared that I might have done something wrong in the process of breaking in the engine. I've read the manual, and watched the dvd, and followed it, but have had so many problems that I have to ask.

I have had big problems with starting the little daemon. And when i got it startet ,keeping it alive.
After watching the DVD a few times after, I thought that the Low Speed/and high speed needles should be in a streight line with the body to be "flush" (factory default), and then noticed my low speed needle was'nt. It was further in, so I thouht it were a mistake and turned it so it were what I believe was flush, but now I realize that it is wrong...

Have been spending about a tank of fuel on just starting it by now... Now i got it running after trying to turn the needle back in, but im not sure if it is back to factory default, and apparrently doesnt know how to read that part of the manual properly :/

Can anyone tell me how to make sure the low speed needle is at factory default?
Can i have broken anything, by doing it?? As said, I am still breaking in the engine (the part where i should run the first lap at low speed (just did)). Any signs to look for?

/artzter

ps. sorry for the badly written english

Edit: Just realized i posted the wrong place, should have beed Nitro Off-Road

Does the manual say your low speed needle should be flush? If you are still breaking in your engine your needles should have been on the rich side, so would say you should be okay.

Here is the part from the manual (attachment). Hope you can read it. Poor quality.


What i foolishly did were to tuen it counter-clockwise to make it flush. But after looking again on that image, it should not be flush, so I tried to turn it back in, but im not sure if I hit the factory default, since I have a hard time understanding what the default are

What I am experiencing now is that when I accelerate the engine stops, which could be a sign of i didnt do this right.. right? And if so, I also understood that if this happens it could damage the engine?

Can I tell somehow if this is the case?

It says very clear that the LSN must be turned in with 1.5 turn from flush.

Setting it at flush just will set it richer so nothing to worry about than only the fact a rich LSN can give troubles with starting and keeping it idle.

Pre-heating is the magic trick to start a fresh engine much easier and it is wise to set the idle a bit higher.

By turning the needle counter-clockwise you made the low end rich, which should not damage your engine. The manual low speed setting is for engine break-in, set the needle flush then turn it in [clockwise] 1 1/2 turns and that's your break-in setting.
