A brand new nitro engine will be set VERY rich from the factory to do the proper engine break-in. The carb needles are VERY sensitive to adjustments. Read your engine manual, and re-set the needles to exactly what they recommend. Also a new engine is very tight. A tip to help you more easier start a new engine is the slightly loosen the glow plug. This bleeds off a bit of compression allowing the engine to turn over MUCH easier. Some guys also use a hair dryer to pre-heat the engine too, this also allows easier starting. Do not adjust the HSN when breaking in a new engine. The HSN has no effect during break-in. The low speed needle will affect break in idle quality. If the engine starts, and idles good but slowly starts to die, and stall, turn the LSN clockwise 1/8 turn, and retry.
