Recently I inherited a Stihl 015 chainsaw that had sat up for a long time. I dumped the old gas out and refilled with fresh gas. The saw started and ran for about 4 minutes and then it died. Since then it has made no effort what so ever to start again. I pulled the side cover off and squirted a small amount of gas into the carburetor and it started immediately and ran for about 3 seconds. At that point I removed the fuel line from the carburetor. With the saw sitting upright and a full tank of gas, there was no gas coming out of the line. I could hold the end of the fuel line lower than the saw and some fuel would slowly drip out. I have not been able to find any instructions on how to remove the fuel filter to see if it is clogged. I did back flush the fuel line with some carburetor cleaner, but it didn't seem to help. So, as a chain saw neophyte, should I see fuel run out of the line when it is disconnected? Since it does start when fuel is squirted directly into to carburetor, is it more likely that the carburetor is plugged? Because this is an old saw, but almost never used, and finding parts seems to be a bear, I don't want to disassemble more than I have to before having a decent idea where the problem is. Thanks for any assistance!

Those parts are readily available at the Stihl dealer.

If it is that old, I would be thinking a new fuel line, fuel filter, and rebuilding the carburetor. But Stihl only sells new carbs. They are normally in the lower $20's for that saw but I can get the diaphragms for $6.

It is not exactly easy to replace the fuel line on these for the first timer.

I appreciate the feedback. Do you replace the fuel line by pulling the line out of the rear of the fuel tank or does the crankcase cover have to come off? With all the crap that poured out of the fuel tank, the line and filter is probably the best place to start.

Get the new molded fuel line and you will see that it goes from the outside in.

The AV mounts need to come out and the tank dropped down to get to the place where the line goes.

If I remember right the fuel filter is a square piece of felt or cotton in the end of the fuel line. Part number for the filter is 1116 358 7800 part number for the fuel line is 1116 358 7700. The carb kit is walbro part number K10-HDC. I Believe the the HDC-17B carb is no longer available from stihl or walbro. You may want to try the way cut4fun has replaced fuel lines instead of using the molded fuel lines. I put the link on so you can see for your self. If you do it this way you don't have to use the square filter and can use any filter. http://chainsawrepair.createaforum.com/ported-saws/molded-fuel-line-fixes/

Once you pull the recoil housing off you should be able to see the fuel line a lot better.

If you ask for an IPL, Illustrated Parts List and SM, Service Manual it will make your job easier.

Guys, at the risk of sounding stupid, I wanted to include a photo to make certain I'm on the same page with everyone else. My saw does not have a plastic tank. The fuel line comes off the carbuerator and goes straight through the metal rear of the gas tank.
It appears to have a big gromet that probably is removed through the rear. I don't want to pull the gromet out only to find that the filter is larger than the hole. My local Stihl dealer said that he wasn't sure if he could still get the crankcase gasket if I had to remove the front crankcase cover. That cover is both the fuel tank and oil reservoir. I'll try and let the photo do the talking. Also I would very much like to know where to get a parts list.

You'll have to look in your Yahoo mail for the service manual and parts list
