So I have been having problems with breaking in my .28 force engine. When I look on OFNA's site it says that I need to adjust 3 needles. the HSN, LSN and the IDLE. I don't have 3 I only have 2, the HSN and the one on the slide carb.. the engine wont stay running and as soon as i give it a little throttle it will die... what am i doing wrong?

If it makes a "gurgling" sound on take off, the low speed is too rich. If it hesitates with a "dry" sound the low speed is too lean. With the HSN, set it at about 2.5 turns from the fully closed position, and if I remember correctly the LSN is set 5 turns from the fully closed position. Also set the idle so the barrel is about 1mm from fully closed.
