Oiler question on Sthil 025

[sonny580]

Just bought an 025, ( ya I know I'm not a Sthil fan,--LOL!) and it acts like a decent saw. VERY hard to start the first time but that was due to it sitting for who knows how long. It starts after 1 pull choke on then next pull choke off since I have reset the carb and did a bit of cutting with it.
Question is it seams to leak chain oil when its sitting like overnight. It makes a mess in that purdy orange case! lol! But anyway is the pump bad or is there some adjustment needed? seals in there? Like I said,--not that familiar with Sthil saws and have a lot to learn about them.
I always use Homelites, Macs., Echo's, and your favorite brand,---POULAN! lol! --
My ms 250 was a joke when I first got it, but after trial and error I fixed it so now it's a great saw. (still pulls hard but that is a ms250 thingy and not a big deal)
Bidding on a couple more Sthil's on a local auction so you never know what you will end up with. That's how I got the 025.

funny, another thread complains his husky leaks and prefers stihl cause they dont
they will leak more in the case cause of the night/day temp differences and its more pronounced in case it seems, plus case will show 1 drop of oil too.
other than caps leaking and/or tank left more than half full will make them leak more

Is it leaking from the bottom or the bar area? If it's leaking from the bottom it may be the oil line or the o ring that goes between the pump and the fitting.

looks to be from the bar area as near as I can tell. Tonight I left it out of the case and set it on a plastic 5-gallon can to see if that makes any difference.
In the case it leaks a ton of oil out overnight.
Caps are tight/dry , tank about a third full.
Might have to dig into the oil pump area and try to find it. also I wonder if cases are a bad thing for any saw? never kept one in a case before.

Five years ago I sold an 025 to a strong lady who loves using the saw at her poultry farm and she can start it. Each year I check on it and the last time I noticed oil in the case. I looked for the leak as you are doing and found a crack in the oil tank cap. It was a small crack in the plastic and really hard to see. I replaced the cap, cleaned up the case, and that solved the problem.
