STIHL FS250 weedeater wont startup?

I have a STIHL FS250 weadeat that wont startup it working perfectly for 3 years until now. Everytime I pull the starter the engine kind of starts then dies off. I think takes more then 30 hard pulls to get the weedeater starter. I tried using it today and no luck at with it starting.

What needs to be replaced or is it time for a new weedeater?

Sounds like the carb needs rebuilt. A carb rebuild kit and an hour and it will probably run like new again.

Of course check the regular stuff too. Spark plug, blockages, carbon build up etc.

The Sthil FS250 is a 2cycle not a 4mix style engine, so no valves on this unit. Some common things to check are. Clogged exhaust screen(15mm nut on outlet of muffler has the screen built on, blocked pulse port in the insulator block. Bad Cylinder gasket also leaks at the crank seals. This unit does have a metal body carb and is easy to clean and rebuild also will want to inspect the special molded fuel line I have seen a few of the older lines get soft and collapse in the tank.
Good luck and keep us posted...
Almost forgot this unit also has a strange kill wire set up to the coil you can remove the recoil and unplug the wire at the coil and reinstall the recoil and retest to make sure its not bare in a spot and grounding out spark to your coil.

STIHL equipment starting issues

Roger Phelps from STIHL here. Wanted to share with you all that we have found one of the most common reasons for poor performance in our equipment has been fuel quality. Not saying that that is the specific issue in this case, however it is worth noting. A recent post on our blog covered this issue. http://bit.ly/Iv7qUJ

Of course your dealer is your best source for determining and fixing the issue.

All the best.

Sounds like a carb issue to me. Once it fires up and you blow it out, it runs right, tells me all the little openings fuel passes threw in the carborator are gummed up maybe from letting fuel sit in it off season. The quick fix would be to buy another one. Sthil is a good brand to stick with
