Hey guys! If I tried to mix 40:1 or 32:1 in my redmax trimmers, would I be able to achieve more power. I know you can usually vary the mix in chainsaws. Is the same true for trimmers. By the way, the owners manual says 50:1 which is what I use as usual. The reason I ask is because it seems that these days the way two cycle equipment is built is more in the interest of the environment rather than in the interest of achieving optimum power out of these engines. I just had a thought that more oil might pollute more but could be better for the engine? I'm no small engine mechanic but it was an interesting though. Thanks!
