The 1985 Stihl 024 AV is 44.6 cc.
50/1
49cc
It stands for Anti-Vibration. I have two Stihl saws made in the 80's (an 015AV and an 034AVSuper). The 034 replaced a really old 041 without the AV, so I can attest that it really makes using the saws a lot more comfortable if you plan on using it for more than an hour or so at once. But then again, all the new Stihl saws have the AV now :o)
045 av is 75cc and the 045 av Super is 87cc.
The Super has 51.5cc
gap is .017
