thankyou all,yes i always keep sharp chain,l am a little annal on sharp chain,always hand sharpen and clean saw after every tank of fuel,or change chain and sharpen when i get home,i never like to push the saw,just let it do its thing,now my uncle on the other hand likes to completely dull the chains,then has me sharpen them,and they can be a pain.......when i sharpen mine after every tank of gas,it usually 3 to 5 quarter file passes to get sharp,on his it always 10 to 15:bang:.....yes on the 28" bar the regular rs work a little better and faster in hard wood to me than full skip,but full skip is sooooo nice to hand file vs reg rs...now on the 36" bar i only have regular rs chain,will have to get full skip for it to try,i always like to have serval extra chains any way....hand sharpen the 36" reg rs chain,and 28" regular rs chain and 28"rs full skip last night,now ready to go again:msp_smile:
