Thread: Stihl 028 AV Super

I just bought a used Stihl 028 AV Super (18") and am wondering if there is a way to determine it's age. Serial number? Also, where can I find an owner's manual? Not available from dealer.

I have purchased the Stihl fuel and chain oil, mixed some premium fuel, installed a new chain, and look forward to years of good service as it has good compression. (got 'er at a garage sale for $125.00 Cdn).

Anything else to watch for on these particular models?

Cheers

I Fell-Welcome to the board. You can get both age (by S/N) and an owner's manual from Stihl. I don't know about Stihl Canada's website, but Stihl USA's website has a page you can go to and order the owner's manual, and you can email them to get the YOM.

The 028 is a fine saw, and you should be very pleased with it. There's been alot of discussion about it on this forum. Do a search, and pack a lunch. You'll be reading for a while!!

Thanks for that. Also, what is the difference between the Super and the Wood Boss?

I used 'er this morning for the first time since getting it Saturday, and with the new blade it goes through wood like a hot knife through butter. Love it!

wb is i believe about 47 cc. the super 52cc. thisoff the top of my head..

I think that Tony is right.
CSCC lists 28AV at 43 cc, 28AV type 2 at 47 cc, and WB at 47 cc. There is no mention of the Super.
A German collectors site i sometimes visit list only one version, 028 at 51.5 cc. That could very well be the version that was sold as the Super in the US.

I know the 028 has a 44mm bore and the super a 46mm bore.

I was using the saw today a fair bit and noticed that it tended to die while idling at times - but not always, and would kinda fall flat or bog coming off idle when throttle was hit - always. Happy as a clam at any higher rpm.

Any suggestions?

Sounds to me like a low (L) screw that might need leaned out a little bit. While it's idling, is it running fast, or kinda burping along, and then dies?

Jeff

Try replacing the fuel filter, which should be done anyways. and look around at the carb settings, it may be slightly lean or rich on the L screw.

Now he's gonna be all confused!

By him saying it bogs and goes flat, I usually associate that with a lower RPM and richer condition. That's just my call on it. I'm just a guy with some chainsaws, and am by no means an expert.

It never hurts to cover all your bases does it? besides, by changing the fuel filter now, its saving time later.

Oh absolutely not. I reread your post and I missed where you said "or rich" and I just read that you advised him to go lean, and I recommended going rich. That's what I get reading too fast. Changing the filter is a good idea. Didn't intend to come across as a know-it-all. I hope I didn't.

Thanks fellas, I'll look into these things. At the time I did try adjusting the screw but it didn't seem to be out of it's sweet spot. I'm wondering if it's something heat related, after she's really warmed up???
BTW, the spark plug looks perfect.

Well I hate to bring this up, but if it's having trouble idling and bogging on accleration, I would also look for an air leak. Hopefully it's just a loose or torn impulse line or manifold. But, it could be leaking oil seals or a leaking cylinder gasket or crankcase gasket.

Thanks thompson1600, I'll look into those things too. It runs like a top once it's over that flat spot off idle, doesn't smoke or anything out of the ordinary. Has good compression too.

The fuel/oil mix is five to one right? (made you blink!)
