I have the 8 port version. It has a strong top-end, but almost nothing at the lower RPMs. If you have a 1/8th scale or a MT, I'd suggest something else like the Wasp or the OS Max RG-X.

I'm guessing the weather in your area has changed quite a bit. I have the same problem. Just re-adjust your low/high needles until you get it to run the way you want. I experience the same problem, as it seems that this engine is really sensitive to changes in the air density and humidity.
