i have a losi 3.4 engine. It is brand new, havent started it yet. Does anyone have any recommendations for starting an engine for the first time?

preheat it and prime it with fuel ( unhook pressure line from pipe and blow into line while opening the slide barrel on carburetor)

make sure you have charged glow ignitor

if you need more assistance contact a local nitro veteran and get more help
