Default RE: Can lean low speed needle damage engine


ORIGINAL: shishtawoo

wouldn’t start using a my electric starter ,which could not produce the necessary force to turn it over.

Oh and i leaned it to the point where sudden acceleration would not stall the engine, i didn’t make it lean as the limiter allowed.

Oh and i have an evolution nx 1.00.
Let's take this in context...

Your electric starter would not turn it over, but you had no problems turning it over by hand... it's a new engine as well...


So, your starter ( not the glow ignitor! ) is not fully charged!

If you have one of those 7Ah or larger batteries, you may have to charge it up for several DAYS.... in my case mine takes almost a week for a full charge... as I'm running a 27Ah battery charged off a 900mAh charger.



You were "driving it around"... the NX limiter does not permit you to run the engine too lean.


So the engine was still TOO RICH on the low end ( which is typical for the NX 1.00 at first, until it is fully broken in... ) even though you have it set not to bog down on run up.

Since you were running it around at almost idle the engine got too much fuel over time, and died out...


Been there myself with this particular engine.

The idle will not really smooth out until you've run a couple of gallons of fuel through it. Until then you'll need to keep the idle a bit higher than normal ( sometimes risking hot landings ) so as not to stall it because of too much fuel.


Doesn't sound abnormal at all.
