Breaking In Engine
 

i followed the instructions to break in my engine. Its says that during one point it will blow out white smoke. well it never did that it just blows out what i think is fuel. and i tuned it how it said. is there a reason for this?

RE: Breaking In Engine
 

Blowing out white smoke means the engine is slightly rich. If you are blowing out fuel, the engine is very rich. But the smoke is also somewhat affected by atmospheric conditions.

For break-in, you want to run the engine slightly rich. To do this, start it up, run it wide open, and turn the needle valve in slowly. You will hear the engine peak (Max RPM) then start to die as you continue to close the needle. Now, you are too lean. Back the needle out slowly, the engine will return to peak. Keep opening the needle until you hear a fair decrease in RPM, but not so much that fuel is blowing out of the muffler.

That's the setting you want to use for break-in.

yes i did that and i was running it just alittle rich and it still seemed like there was alot of fuel coming out....is that normal? there was a thin film of fuel on my plane? so the white smoke may not come out at all depending on the atmosphere? thanks for the help

Some fuel blowing out is normal. After a day of flying your plane will be pretty gooey. I've heard Electric fliers refer to our planes as "Slimers".

I hate that term, "Breaking" in. It sounds so ominous and negative. Shall we use "running" in instead? Or maybe running-in is what the electric guys do to their "motors" and the smoke huffers do the breaking-in thing to their "engines"? [X(]
