Hello, I am a novice with a chain saw but learning quickly. I purchased a Poulan 42cc with a 18'' bar. It was one of those day after thanksgiving specials with a case and sharpner for $99.95 deals but looks just like the Poulan Wild Thing. I love the saw. My neighboor is amazed at how fast it will rip through green Red Oak. The problem is I have to keep the blade super sharp for it to cut at all. I immediately purchased a Home Depot replacement chain because the one that came with the saw went dull within 30 seconds of meeting Red Oak. I am assuming it is safety chain as it is just a made in China Home Depot run of the mill chain. The problem is I can only make 2 or 3 cuts in 20"+ Red Oak before the chain becomes dull and you can feel it stop cutting. The wood is not dirty and I am not hitting the ground with the chain. The trees are just dense and dulling the blade. So finally I am getting to the question. I can not make this saw kick back no matter what stupid stuff I do with the blade. I am afraid that a 290 Farm Boss or 455 Rancher will not be nearly as forgiving. I am assuming that more power and bigger teeth= more kickback. My questions are am I right is assuming that a bigger saw with a chiesel tooth blade be more likely to kick back than my smaller saw? I'm assuming that is what safety chain is, anti-kickback, right? It is not a matter of strength. I hate using my Milwaukee Skill saw because it kicked back on me one time. No injury but I guess it is just a mental thing. I am also assuming that a chisel chain will stay sharp MUCH longer than my Home Depot Chain. Thanks
