Affirmative on everything you mentioned! if it is left leaking, it will just fail again! Decomp is no big deal to replace, the rest is a little more problematic but still needs to be done. You could replace the decomp with a blocking plug $2-4 from dealer. Leak from gen mount hole is beyond my knowledge for this model saw.

My experience with other saws that have a provision for mounting generators under the flywheel is that the holes for the mounting bolts are usually blind. If the other holes are not leaking then perhaps the leak could be repaired by putting a bolt in the hole with some red Loc-Tite (WAG)! Does not make sense that Stihl would have left a mounting hole open to the inside of the crankcase without providing a method to seal it off!

Well they are blind holes. I can still see the end of the hole. Don't know if they they got in there to far with the drill and tap or what. It is a very slow leak. For the decomp the one on an 084 is coarse thread. Not like the ones for 260-660. I usually replace all the above mentioned stuff when I would do a top end replacement. But the guy I am fixing it for does not like to spend any money.

Then tell him it isn't worth fixing and don't waste your time and his money.
They are WAY too expensive to half ass.
Plus, it will be your fault when it fails again because he didn't want to spend the $$$ to fix it correctly!

Very true. Talked to him yesterday and let him know what I thought and have not heard how he wants to go yet. Hope he will put the parts in the saw. Should make a real nice saw for a long time.

Perhaps if you could find three of the correct screws that were short enough that they would not interfere with the flywheel, you could use them and sealer to block all three holes and stop the slow leak. Not much $ and would keep the saw from coming back.

Like MS61 said above. If I get a saw that needs something and the owner does not want to pay for, I'll put it in anyway at my expense just to keep it from coming back, with the owner whining at me! You cannot work miracles but you can avoid the whining!

084 flywheels
« Reply #126 on: May 05, 2014, 11:02:12 pm »
Are there differences in early vs later 084 flywheels.  Do all have the small "module" in addition to the coil?   Thanks. Adam

I know this dont answer your question. I remember 3 coils and 2 flywheels. Thinking 1 of the flywheels had dual key ways. 

I would swear 1 of my 084's didnt have the small trigger.

I'll go look at IPL's etc.
I gave my hard copy of 084 service manual away. So cant look there.

Kev, the one I have here is a basic coil/flywheel set up like the 088/880. Sold one a while back that had the small metal module mounted near the flywheel.  Reason I ask, is that Adam32 has one he's putting together that seems to be way too advanced... I'll check part numbers on mine tonight

Stihl 084 404 stock
« Reply #129 on: August 13, 2014, 01:25:37 pm »
Found a old video of the 084 I rebuilt stock that Adam Clarke had gave me at Chardon and then traded to other Adam out west. 

Just stock 084 .404 chain and ole spruce test cuts after rebuilding.

Stock Stihl 084 running stihl ES bar, 7T sprocket and  404  woodsman pro chain.  ( CHAIN is crap out of the box )
2 cuts let it feed, 3 cut I  pushed it hard into knots I cut in half.
