Nitro RC Carburetor Cheat Sheet
Here is a small cheat sheet I made for quick reference when adjusting the carburetor (High Speed Needle and Low Speed Needle) on a nitro engine. These are the basics on carburetor adjustment and are a must for anyone interested in nitro RC.
These adjustments apply to the HSN (High Speed Needle) and LSN (Low Speed Needle) found on the carburetor of a nitro engine. These regulate the proportion of air vs. nitro fuel that enters in the engine for combustion.
