Craftsman saw's seem ok for being a better poulan… I used to use a 42cc for years but I hated it..... Leaks gas where the two halves were seamed together... the "heavy duty" crankshaft broke when it was stuck in a 6-7" tree.... It was a free saw so cant complain too much.... Main thing for a chainsaw is power, anti-vibe and a good chain or two. If you have those 3 things then you can cut all day. I would still buy a stihl over anything else if I had to buy a new saw from scratch though.
Ebay has a good deal on tune up kits for anything with a small engine. I usually buy online before going to a local store because for the price of 2' of fuel line, a spark plug and an air filter that you bought locally you could literally buy the fuel lines, primer bulb, air filter, fuel filters, spark plug AND the carb for the same price or less than what you paid locally.... I bought a pack of 4 most common fuel sizes for $10 and it was 4 different lines about 5' long. I paid $10 for 4' of just one type of fuel line at the store up the street....
