Default RE: ~Evolution 61NT engine feedback needed~

These Evo engines have prooven to be pretty nice engines so far. Reliable, run well, good power. They also respond to a tuned exhaust system nicely.

Considering what an old K&B .61, OS61 FSR, OS61FX and similar engines historically run like turning an 11x7 - 12x6 prop, on a stock muffler, the Evo .61 seems to be right up there.
