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

Hi all
I’ve recently pick up a baja hpi 26cc off eBay he had changed afew things exhaust air filter and afew bit on the body but I’ve took it out and it was abit boggy on top end and slow to pull off so I thought afew adjustments on the needles and ill be away but after factory setting them it wouldn’t start the only way it would start was to put them back and that is nearly all the way in the H needle is basically all the way in anyone got any clues???
