Ladies & Gentlemen,
I have a 11 or 12 yr old 025 and a 10yr old 390 that both "died" on me.

I need parts for the saws or advice as to if I should waste my time fixing them. I have found used, new, & aftermarket, parts to fix both saws for about $450. At what point is it better to buy new? it doesn't seem there are a lot of parts to replace & get 10 or more years out of them.

I should say I don't want to spend the money on two new saws to replace these two saws.

Here is what I need:
025~ cylinder & piston

390 cylinder & piston, flywheel (don't ask why :-X), coil (don't ask why :-X)

I have been told to stay away from aftermarket cylinders & pistons, but no one gives me a good reason or personal experience, just hearsay whore stories.
Thanks in advance for the help

 If your going with OEM parts you may as well buy a new saw or saws, OEM Stihl is way to expensive.   Steve

So, are you saying aftermarket parts aren't a bad idea? Have you used them? Do they last as long?

Unless you have sentimental feelings for those things you have to ask yourself something .Even in good running condtion are both of those saws collectively worth 450 bucks ?Some might say yes but my money is that the majority will say no .

I would buy a new saw of the size you use most and a used saw from a reputable dealer to fill my other needs.

My thought process was, spending $450 to fix 2 saws, which would essentially make them almost new, is worth it since the motor is the only thing wrong, which is cheaper than two new saws.

I just didn't know if aftermarket parts are reliable. Also wondered if the the new MS362 and/ or MS391 is that much better than the MS390.. Make since?

I thought about just this too....

Are you doing the work yourself? If not, does that $450 include labor? If you're having a shop do it, the labor may be a deal-breaker. I wouldn't rule out a good used saw such as an older 036 Pro. It's a lighter saw than your big one and not much heavier than the small one and will outcut either. I watch Craigslist and sometimes see them in very good shape for around $300.

I just put together an 039 out of parts I got from Asia. It's the second one I've done and have been very pleased with the results. I think you could probably get one of your saws going for less than $100 and then you can make your own determination as to whether aftermarket parts were a good idea. Is your flywheel junk or just has an issue?
Too many chainsaws, not enough wood.
Stihl, Husky, Craftsman, Mac, Homelite, Poulan. Some live here, some just passing through.

I broke one of the fins when I was tearing the saw apart. not a big one, but am wooried about it throwing it out of balance & scraping the crank & bearings.

Don't rule out used OEM parts either, not nearly as pricey as new Stihl parts.

There's all kinds of options rather than new OEM parts .

One is surfing a dealers dead pile .Find a couple saws with compression and part them out .They end up coming in for repairs which cost more than the saw is worth .The dealers end up with them and usually sell them relatively cheap .Oh some of them I'm certain try to get top dollar prices .Depends on the dealer .They don't rule market place though because there must be a Stihl dealer every ten square miles .If one won't deal chances are the next one will .

Considering that a new MS390 (391) is around $550 it would be a tough decision to spend $450 on the 10-year-old saw.  That said.  I have a 390 that is about the same age and it is a very reliable saw, tho it's a gas hog.  So. I understand why you are considering to fix it.
It's the going that counts not the distance!

You certainly can not repair either saw with OEM Stihl parts for a reasonable price. If you need a cylinder and piston for either a 025 or MS390, OEM parts are going to cost as much as a new saw. There is a choice however. You can buy a complete motor for a MS390 for $160 from one of the sponsors of this site. It is a bolt in complete engine all sealed up and ready to go. I did also see a brand new complete engine for a MS250 being offered on a auction site for $150 that will fit your 025. That is also a bolt in, ready to go complete engine. Both of these series of saws are easy to work on when it comes to replacing the engine. While you are at it you might as well replace the carb manifold, impulse line and fuel line while the saw is opened up.

Doesn't feel good to repair something with your own two hands ?

I usually do feel good when repairing something myself.

Good golly miss Molly ,that much ?My Lawd I can remember when you could buy an 066 for just a tad more than that clam shell thing .Wow!

I guess I'm blessed with the ability to turn a wrench .For that amount of money I could shake together 3 or 4 from a hodge podge of parts .Might take a while to round up all the parts though .

Here is a MS 390



And here is a MS 250 motor



Both saws are easy to work on
