Stihl Weedeater Problems
I have a Stihl weedeater that don't run worth a damn this season and hopin somebody can tell me what all to check out on it. It's about 4 years old and not much use in it, wear's me out to use it so I don't use it much. It's a model number FS-250 with a blade on it. Takes forever to get it started and even when I do and it's warmed up it dies everytime I let off the trigger. To get it started I have to keep pushin the primer bulb until it get's warmed up and even then I have to run with the choke on. I've cleaned the plug, just put a new one in it last year and it has fresh gas for the season. This was an expensive little toy to have these problems with.

Need to adjust the carb. On the side of the engine you should have a plastic fuel screw, one red and one white, unless they've been removed. The red one, turn it all the way to the (R) (I believe it is) see if that helps. If not, those plastic caps pull off and you can get a little more adjustment out of them.

Fianlly got around to this today. The only adjustment screw on it turns the idle up and down. Everything else appears to be sealed. I'm sure theres a fuel filter in it someplace but I sure can't find it. I haven't stripped it apart yet lookin though either. I'm hopin somebody on here can tell me if there is one or if it's inside the fuel tank or somethin before I get around to tearin it down and find out it's for nothin. I thought at one time we had a couple Stihl dealers on the site.

Alright, your fuel filter is in the tank, there's a fuel line that runs into it and it'll have a fuel filter on the end of it that dangles. They're usually black with screen, but I'm a lot more familiar with saws. You will have 3 adjustment screws on the carb. H, L, T; High, Low, Idle. They may still have the limiter caps on them, in which case, you can only adjust them so much without removing the caps.
Make sure your choke linkage is moving freely. Your a long ways away from me, otherwise I'd help you out. I'm sure as long as your jug and piston are ok I could have it running in 20 minutes. Once you find your carb screws, screw them all the way in, then turn them both out 1 full turn. Try running it at that setting, it should be real close to stock.

Went to work on this thing today and tore it apart. Must be some changes made in the new 2 stroke engines. Pulled the carb apart and the only adjustment screw on it is for the idle, everything else is internal with no adjustments to be made. Also no filter anyplace on this thing.
I played with the idle screw, sprayed some carb cleaner into the piston and ran some Sea Foam through it. No changes. I can make it run by keepin the trigger pulled or by pushin the bulb continuously. Guess it's shop bound. Damn I hate spendin money like I had any.

Filter is always in the tank, but I guess they stopped them on the trimmers, news to me. Sounds like one of your jets is clogged, or your float is stuck, hence why pushing the primer bulb would keep it running. Could also be a fuel line thats cracked, fairly typical.

Oh, and skip the Echo, ask a pro what they use, it ain't Echo. Husqvarna, Stihl, Redmax, or even Shindaiwa... Stay away from Homelite, Poulan, Crapsman, Weed Eater, or other junk brands.
Also keep in mind, all the good companies have a Pro line and an "Occasional Use" line. If you want something thats gonna last more than a few years, get the Pro model. It may cost 50% more, but it'll last 200% longer. Its just like chainsaws, the best homeowner model, is a pro model. Thats pretty true for everything, hell, look at our trucks. They might cost 20% more than a gasser, but they'll last 100% longer!
