Spool up is slightly slower, but not too bad.

I got a big surprise today. I finally made it thru my first jug of break-in 32:1 lawnboy. I switched up to 50:1 amsoil and I lost all my power. No more pull out of hover. The engine just hates it. So I am going to mix up a gallon at 40:1 and try another gas station. It was a very dramatic difference in HP. I thought i would pick up a few hundred rpm. I did adjust the needles and it only got worse. Hopefully it is just bad gas or it is that sensitive to the oil mix.
