I don't have the saw anymore, so I can't do a picture. I cleaned out the area where the plug should be with brake cleaner so the epoxy would stick to the plastic. I stuck the nail in the oil port outlet under the clutch cover. I probably sprayed it with WD-40 so it wouldn't stick to the epoxy. I worked some JB-Weld into the plug area making sure not to put in enough to stop up the oil outlet for the chain. I left it overnight for the JB-Weld to set up and then pulled out the nail. I really only used the nail to make sure I didn't do something stupid to block the oil outlet. I was afraid the JB might flow down the tube before it set up.
Expanding the thought a little, a short sheet metal screw with some epoxy on the threads would probably do a nice job too to seal it up. I didn't do it that way, but it would probably be a better fix.
 
It almost looks like a set screw. I would think a set screw that is a little smaller with some teflon tape on it will work.

I was in a pawn shop on a whim two days ago where two 025's sat, one sitting in a puddle of oil and the area all around and under the muffler was oily. The exhaust screen was pretty oily too and I thought obviously something was wrong, along with maybe way too rich mix..... now I have a fair idea of a big part of the problem. Wish it were closer to have another look! Way too overpriced though anyway. Thanks for the lesson gang!

New to this site. Had the oil plug on my o25 disappear. My local shop didn't have the set screw so my quick fix was to use a piece of fuel line that just fits inside the passage and run a sheet metal screw into the end of the hose. It expands and seals it nicely. I used the tip of running a nail in the oil exit port to make sure I didn't insert it too far in before tightening. Easy to make a spare or two to keep in the tool bag in case it comes out. I'll keep hunting for the set screw.
 
Working a on a neglected 025 for a friend.
"THIS!"
plug was gone.
Used an M6 x 8 allen head, cuz I got a lathe, I turned the head down so it fit easily, had just enough meat so the allen wrench would turn it. Shortened to about 7mm, tapped the plastic hole a bit, dug out the plastic "string" from cutting the thread, installed the screw. Looked in with the boroscope, piston and bore looked very good.
Cleaned up the fuel cap seal, replaced the fuel line. Cleaned the air filter, it was plugged solid with sawdust, the incredibly dull chain and never filed rakers were making, and bingo bango a like new saw, was pulling through 8" of dry gray elm smooth and easy.
Thanx guyz.
