I have a parts/assembly list from 1988 for this chainsaw from: http://mcculloch.motoruf.de/spell/get_file.php?filepath=/Mipl/ps100ser.pdf and also just found an owner's manual from 1987 for the Eager Beaver/MAC 100 series here: http://portablemedia.manualsonline.com/mdownloads/0b32d5b1-12ff-47cd-bb41-c5a26614a44c.pdf My questions are: **What are the differences between the MAC 100 series and the Eager Beaver 2.0 60012312? **Does the same manual serve both models, as the parts/assembly list appears to? **If I haven't located the correct operator's manual for the the Eager Beaver 2.0 60012312, does anyone know where I can find a free one online? **This chainsaw was in my dad's basement and hasn't been run in years. Most of the postings I saw online while looking for an operator's manal complained of problems starting the saw and/or restarting it after use. Is it worth putting time (and probably money) into this chainsaw? Are some models easier to maintain/adjust/run than others? Many thanks, in advance, for any help anyone can provide!
