try leaning it up just enough to get it running, try leaning it up a quarter turn, and if it still wont keep running after a few tries. pull the plug and turn the motor to get the extra fuel out, and turn the hsn another eighth of a turn. just keep doing until it will start. also check your plug, to see if its disformed.

Make sure you are at factory needle settings for both LSN and HSN. Also check to see that your idle is proper (~1mm). If you can't get it to idle without stalling out you'll probably have to lean the LSN untill she runs consistantly.

I had the exact same issue when I started breaking in my RB earlier this year. Once I got it going and the needle position figured out she idled like a dream.

Don't let it get you upset. This is all part of the hobby. Believe me, it's very satisfying once you get her to idle a tank w/o stalling out. It'll take some fidgeting but that's what the hobby is all about.

LSN: 4-4.5 from closed
HSN: 4.5-5 from closed
Idle: 1/16" gap
Normal engine operating temp. ~280*F

the same thing happened with my hyper 21. i eventually had to turn the hsn a full turn to get it to run. check what factory setting is, and lean it from there to a point were it will run. it took me awhile to get it to run but trust me its all worth it.

Preheat the engine before you start it, works wonders. A hair dryer will do just fine.
