Hi, I hope this finds you well , my question is what are stock needle settings for HSP 1/10 nitro rc truck .18vx engine ??? Kind Regards

Out of box engines are flush with needles, and 1.5mm Air gap( throttle opening, idle speed). LSN turn CW till bottom out, then 4 turns CW. 3.5 to save time.

thank u for your coopration what about HSN ????

Sorry misstated. HSN Flush or 3.5 CCW from closing. LSN Flush. Air gap 1.5mm. Note that this doesn't tune the engine, but it does get it running. Your manual should these starting points.

i checked my manual its says "2 or 2 1/2 turns from fully closed postion" is that for HSN or LSN or Both ???

HSN Fine. LSN always depends on location, altitude, Weather. LSN always the last adjustment. Where are you located?
