a couple years ago when the 440 stihl could not be bought new, i built this one from parts ,i did an 044 also from parts ,it would have been cheaper to buy a new saw and all of it be new instead of most of it,the last 440 i built i got a complete saw that was locked up ,tore it down it lost a piston pin clip ,i had an early 10mm cylinder ,bought a piston ,a new handle and handlebar just to freshen up cosmetics ,rest of saw was pretty clean had about 650 into that one building it ,had over 800 in each of the others bought part by part
