What ratio of gas to oil do you all use? It seems like more and more equipment these days are going from 32:1 to 50:1. I run 32:1 but i think its too rich for my redmax trimmer. But my homelite hand-held blower says run 32:1. Rich is better then lean, isn't it? guess i could go in between somewhere like 40:1 but i don't wanna damage anything. Thoughts? Opinions?
