You have 2 carburetor adjustment needles on your HPI Baja Stock engine.
Your (HSN) High Speed Needle Factory setting is 1.5 turns out from closed. The HSN is the longer of the two needles and is the left of the two. Its marked on the housing of the carburetor housing with an (H)
Your (LSN) Low Speed Needle Factory setting is 1.25 turns out from closed. The LSN is the shorter of the two needles and is the right of the two. Its marked on the housing of the carburetor housing with an (L)
Gently screw in the needle intil it JUST closes all the way. Do not try to tighten it up or snug it down. Screw it in JUST until you feel some resistance. Look at the slot in the screw or find a mark on your screwdriver handle and back the screw out to the EXACT amout of turns listed for that needle.
- HSN: 1.5 Turns Out
- LSN: 1.25 Turns Out
