The Stihl 034 AV is a reliable saw that has done satisfactory work on trees up to 20 or 25 metres tall with a considerable diameter. Never had any problems with it.
56.5cc, 3.0kw, 4.1hp, 13000 RPM.

The difference is in the motor size.The 034AV is 56.5cc (cubic centimeters) and the 034 Super is 61.5 cc (cubic centimeters). The 034 Super has a slightly larger motor, and therefore it presumably also has greater speed and power.
Stihl has only grudgingly ever published HP figures, for a long time they were only in the kW ratings indicative of Europe. The machine has approximately 4 HP.
I have an 034AV Super and it came stock with a 20" bar. An 034 isn't quite as powerful (56.5cc vs 61.5cc), but a 20" bar should still work great on it.
The 034 takes either a .325" or 3/8" pitch chain. My guess would be 3/8 .050 go to chainsdirect on eBay chose the chain for youre bar size.
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)
