stihl 020 av

My first post. I just picked up a stihl 020 av can any one tell me how to split the thing apart? I just can't figure it out I have the screws all out i think. Can anyone give me a step by step instruction on how to separate the two halves. ??? thanks I hope

There are three little saws which are the most pain the behind to work on and the 020AV happens to be one of them .The other two are the Mini Macs and the Homelite Xl supers and Xl-2s' .

Where to start ,well first of all you need to get the shrouding off which is a chore in itself because the danged thing is held on with straight slotted screws which don't like to come out .You'll just have to fumble with it because that's about all I can say about them .I never completely split one only took one down only once to get at something below the shrouding .

If you are just peeling it down to get to the seals you don't need to split it .I've got a few pictures if you need I'll post them about changing the seals on the old 020 av .

Thanks so much for the come back Al. The first thing is the plug wire looks original would like to replace it. Also do i need a original fuel line in the tank because there is just regular yellow line in it now. Have yet to run it, it ran on a shot of fuel but the past owner said it would run at high speed with the trigger pulled but won't idle. Just preparing my self for a teardown

I started wrenching in a Stihl shop in 1975, I cringed when an 015 or 020 came in. Between those, the McCullochs and Remingtons I learned to hate small saws. :D

If it'll run on a shot of fuel you might try just a carb rebuild along with new fuel/impulse lines. I wouldn't look to tear all way down unless ya have to. I got my 200 this summer with everything from the intake back off and in pieces, guy said it wouldn't run and he had rebuilt the carb. I did the carb again and got it together, runs like a champ. Sweet little saw I will say. ;)

The problem is i have to pull the whole thing apart to get to the carb or do i no access to the carb at all

You don't have to peel it down to the bones to get to the carb but if memory serves me the shrouding has to come off .

These things might be the fore runners of the 020/200T but they certainly are not as user friendly regarding repairs .The later models are by far the easiest saws Stihl ever made to work on and this one is among the worse .

Coincidently fact is I have one that needs a carb rebuild and as soon as I get my mind right when I peel the shrounding off this time all those slotted screws are going in file 13 and replaced with torx heads .

Before you even start blow all the crud off that thing with compressed air so you can find all the bolts because they hid some evidently in order to drive people nuts trying to find them .That plan worked .

As far as fuel lines you are probabley better off to replace them with OEM lines .Might cost a bit more but this is one saw you don't want to wrench on any more than you have to .

For a little saw though they cut allright ,not a 200T but not bad .

I might be wrong, but I remember them as not being really bad messing with.
To get them out of the shell you need to remove, I think, five screws, one from the right, underneath the muffler, one at the top, underneath the handle, two at the front from the left, one inside the air filter housing, and remove the two nuts holding the carburetor. Then remove the choker arm, and take care with the throttle linkage.

Ok, I might be wrong. Haven't had the pleasure of working on one for more than 25 years.

Thanks again Al
Well i couldn't get her apart so left it alone. Just wanted to clean it real good anyway. So i cleaned it the best i could put all the screws back in. Fixed the boot end of spark plug wire, that is what needs to be replaced, looks original, a little melted but not showing any wire. Adjusted H n L to spec fired right up idled fine messed with the LA a little to get the chain to slow a little rapped on it a few times but won't idle wants to stall. If i feather the throttle about 6 times it will idle again. old plug 87 octane not stihl 2 cycle. just wanted to see if it will run. Also like i said fuel line in tank is just a regular straight hose not OEM. will change that soon. Pain in but to get that on too. Had to cut straight line and reattach. What chain does this saw normally run? The number on my chain is 3. It is a still chain. The bar has these numbers on it Stihl 9.81 and below that is 5 000 6413 any ideas??
thanks again
