DA-60 How much burble do you have??
I am getting great power out of the Da 60 but was wondering if anyone else had a burble. Or how many gallons is it taking to get rid of it. I was running about 6800 rpm hot with a 24a vess @ 3700 ft. The engine starts great and transition pretty good but I can hear a burble at wot. Thx.

Lean it out a bit

Is the breakin finish? Because, if your spark plugs are whitish color with hi temps you need to richin it out, and the burble will go away when the breakin is complet

I was hoping it goes away but was curious to know what other people are seeing. And how much fuel it was taking. I have the the plug golden tan right now. But when I was trying to lean out the burble i went as far as a white plug. Burble was still there.

Be patient!!!! let the engine come to you! Don't take a chance and stall the engine in flight!

If you have a good idle with excellent transition at mid-range and a steady high rpm the burble and breakin will take care of it self in the AIR NOT ON THE GROUND!!!!!

it sounds like you have a intermitted high speed miss to me.dosen't sound like any burble i have ever heard.i would check all wires,battery,switch,ignition cut off if any.try a different battery and plug it direct to the ignition and see if it is still missing.

The video shows a lean condition also. Burble hapenes in the midrange not on high end. |

+1 on this, what Voltage pack are you using? I have seen this with slightly high / close to max Voltages on freshly charged packs. I solve it by running a single diode inline.
