Stihl 010 Chain Saw

caseyj · 1st October 2011, 10:28 AM

I am looking for a pdf for a repair manual on this saw. The current question that I have is regarding gas leakage out of a port next to where the gas line enters the tank. I never noticed this opening before but I assume that it must be a vent for the tank. The problem is that gas leaks out of this opening during use and there must be a part to prevents this?? Hopefully some of your experts here can answer this question. Thank you.

If I remember right they have a grommet that the fuel line runs throu.

redneck -

The gas line has it's own port for entry into the gas tank. The port that I am referring to is about 3 inches to the left of this port. If I had a diagram, or someone who owns this saw, they could than tell me what this port is for. But ??

I've seeen other posts that indicate that they have a problem with gas leakage on this model of saw and I suspect this is where it comes from. Thank you for your reply.

Do you mean the breather just above the clutch?

It should have a bit of fuel line coming out of there.

009, but nearly the same saw.

The hole that I am referring to that leaks gas is to the far right of the gas line.

There is duck bill valve that fits in there to vent the fuel tank.\

Sorry, the hole is to the far LEFT in the picture.

I posted this question on another forum and the consences seems to be that this is a barometric pressure relieve port. It was said to plug the hole with a short piece of tubing and place a threaded screw in it to prevent the gas leakage. Evidently, by leaving the screw partly turned out it allows the tank pressure to equalize for different locations in the world. I have something similiar to this on one of my bigger saws.

Thanks redneck. I think you were describing the same fix.

Great responses and thanks to all!
