stihl 028 AV super woodboss specs?

[Jack.Resar]

I just picked this saw up it runs but I was told it needs a new piston. It's a Stihl 028 AV Super Wood Boss. Can anyone tell me if it uses the 46mm piston

pressure and vac test. then take the jug off and measure it. There were so many variations of 028 I would never assume anything. and measure every time.

Sorry I know this post is a few months old but, If its a 46mm (this piston has a slight dome in the middle of it) then it is indeed a Super, 44mm (this is a domed piston) was the AV electronic and the 42mm was the early model with the metal tank and no chain break.

I just did two 028 refurbs and used both Stihl and aftermarket fuel lines.

Both lines were about 1 1/2" shorter than in my opinion would be correct.

Likely starve for fuel at 1/4 tank.
