A carb kit and fuel line might be all it needs.

I found the air vent loose and it was the source of the raw fuel.
It runs a little better, but still dies eventually.
The other needed a new primer bulb. After I replaced it, it ran like nothing was wrong.
Both have sat at least 2 years previously.
The attachment you provided was very useful, thanks!

Howdy all. I own a Stihl FS56RC weed whacker. When it works, it works like a charm....but there is a lot of operator error involved.

So the source of the leak was a cracked diaphragm. It takes so long to get parts mail-order, I have started to search out locals for my parts. A local has the rtebuild kit for the same price online, but I have to drive 50 miles round trip to get it! But, when I get home, I have it, so that sure beats waiting weeks.

Any mower shop will have a bunch of Walbro WAT kits, they are very common.

It's a Walbro, eh?
It has 'Stihl' embossed on the diaphragm cover.
I may have a closer source, in that case!

Thanks! Just for giggles, what would be the determining factor between which of those three I would get? The local guy seemed to figure it out when I told him I had the big knob choke lever on the back of the unit.

On the side of the carb, right near the fuel inlet nipple, you should find the model number info.
Here is a nice lookup. The wat-20 kit is what you need.

Thanks for the chart, but super thanks for telling me the number.

Hi, I'm Dave and I have a Stihl FS44 string trimmer I bought new in the 1990's.
