Most of the saws I got were 35cc or under. Keep in mind that different brand names will have different manufacturers for the same item based on year or even the specific model. Very possible your saws aren't the same. Also possible I ended up with like 5-6 saws of the same design and 3-4 had blown engines by coincidence, though that hasn't happened with anything else.pfun, once again we differ.... I needed a cheap throw away saw that I could throw in my cabin box with the tow straps, come along, clevises etc. I found a refurbed Craftsman 42 cc on line for $69 shipped. For the last 5 years I have pounded the living hell out of that saw. I've destroyed at least 6 chains on rocks and nails, I twisted the hell out of one bar, another bar I completely wore the tip out stump grubbin' tag alder and it still hasn't died. The one thing I have found is that when it's warm it doesn't like to be left baking in the sun. I'm guessing vapor lock, but it will give you fits if you don't move it to the shade to cool. It will absolutely not start if it's left in the sun. I figured for 20% of the cost of my little stihl if it lasted a couple of years I'd be money ahead. Guess I got lucky. I have another old Stih 038 that I picked up cheap and got running really well. Part of that deal was I had to take like 5 other saws 2 of which are Poulan Wildthings. Both of those run well and the rest I haven't messed with. For $75 buck I was happy. I'm going to give my kids the saws to carry when they come up to camp just in case they run into a tree over the road.
