Stihl 034 Super AV EQ

2 smokes get 2 smoke oil...engine oil will work fine, just smoke like crazy on startup...and blow black slobber all over your nice clean saw...

 

Two stroke oil, yep.

 

10W-40W out in the garage and barns
2-stroke oil in the basement shop and at the drill press

 

2 stroke oil for 2 stroke engine assemblies.

 

I don’t think it matters a whole lot what you use. It’s going to be washed out in the first 10 seconds anyway.

 

I ordered (2) of the 1125/10 annular buffers but the eBay seller sent me 1125/06. Is this going to be a problem? The existing buffers said 1125/10 on them. What's the difference between them? What's annoying is on the eBay auction it clearly showed the buffer reading 1125/10 on the bottom of the auction pic so I don't know why they would send me the 1125/06 unless it was an honest mistake. I messaged the seller already.

 

No worries. They should just be degrees of “hardness.”

 

I sometimes match them up based on the ipl. Sometimes I don’t…

 

That makes 100% sense. Upon closer inspection the 10 is indeed harder. Has a big blue plastic insert vs the 06 which has a much smaller diameter plastic part and more rubber.

 

Thanks Buckthorn Bonnie.

 

So if I'm understanding this right, if you are looking at a 10, the insert will be much larger and harder than when you see a 6...

 

LOL Birds and Bees, 101 LOL

 

I wonder why 2 of the av buffers on the saw were 10 and 1 was 04. Seems kind of weird but most likely a previous owner had one replaced?

But in this diagram it shows 04, 06 and 10 being an option for position #1 (2 places) but only 04 and 06 as an option for position #2.

The hard/normal/soft AV system listed out. Still doesn’t really answer your question, though. I’ve used most of the AVs in various locations. I’m pretty sure that I’ve noticed slight differences in how they feel. Are they the same dimensionally? Most are…

I also use used AVs if they’re not torn or stretched out. I’ll try to get some comparison pics to ya but feel like you’re good to go using the ones from eBay.


When are you planning on pulling it together?

 

The 06 and the 10 seem to be dimensionally identical. I'll keep the old ones as spares just in case. The ones I got are original Stihl.

I will probably do it in the next week..... I really wanted to get my wood all cleared away which I did the other day....so now I have time to clean up the garage and organize the bench a little.

I'm still a bit confused about the whole process. Should I replace the piston needle bearing? It seems fine but given that the saw was run into the ground maybe it's a good idea to do that now rather than later. Should probably order the clutch needle bearing as well. I want this saw to last!

 

They are probably OK if they are tight, clean, and not blue from heat. But on the other hand, those bearings are cheap insurance for peace of mind / longevity.

 

Good for you. There's one more Stihl thats going to continue to have a good life.
I tried to restore a 020AV and eventually just had to give up on it.

 

I saw your post. I don't think you should give up! You can buy a cheap carb on eBay or Amazon and see if that works. If it doesn't, it won't cost you much (~$20 I'm guessing). That 020T is a super sought after saw. I think they go for $500+. Did you check the rings on the piston? I didn't see any mention of that in the thread but maybe I missed it. My rings on this saw were rotating because the little notch had fallen off. I don't even know how to do it but you can do a pressure test and see if you can isolate the air leak. It could be the bearing seals. They don't look like fun to install as they rip easily if pushed too far based on videos I've seen.

Thank you but I haven't counted my chickens before they hatch! I still need to put it back together but first need to scrape off the old gasket residue from both sides of the case.

 

Thank you for the suggestions and encouragement.
I'm actually a very persistent person. I don't really give up on things and in general I'm very good at fixing things.
I'm just a bit pizzed off right now, and I know when to walk away.

I'll get back to the 020 eventually.

 

I'm almost ready to start putting it back together. Had to deal with patching up some weeping concrete blocks in the basement with some hydraulic cement and drylok........but more importantly I got my workbench all cleaned up. Hit it with the belt sander and it's unrecognizable now. The top is solid oak with some obvious repairs that were done to it previously. I put one coat of Tried and True finish on it thus far.

Here's the thread on the workbench but I figured I'd throw in a pic here. Second coat of BLO goes on tomorrow and then I'll be in business.

Before



Sanded and cracks enlarged with a chisel to give the bondo some room to adhere to.



Holes enlarged with a drill bit for the same reason.



And after:

Holes plugged with bondo.



Sanded and cleaned with mineral spirits



First coat of finish.
