The 661 ported is a good runner but I can beat everyone I've ported with a 660 using less fuel and less compression.
It's good to hear someone else makes rippers with lower compression. Both my 371xp bb and 268se bb just plows through wood, maybe my compression tester is broken, but I can start both saws easily without pushing the decomp button.
