I finally got a chance to make a test stand and tach my little Echo Kioritz today!
Still all stock for now but I was supprised. It turned a 16x8 APC at 7000 rpm then
I took the little deflector plate and spark suppressor screen off the muffler and it
turned 7800 rpm all with my Tower Hobbies digital mini tach. I don't know how
accurate it is but it seemed pretty consistant. I have a larger carb to try and I am
going to experiment with some different muffler designs. I will post #'s when I do.
