Husky 51 fuel leak

[John Mc]

I picked up a husky 51 for a friend recently. After taking care of a few minor issues (threads on bar oil cap stripped, throw out the worthless safety chain and replace with chisel chain, etc), I noticed another problem:

I found a small amount of fuel mix under the saw when I picked it up. Saw had been stored on its side, with fuel and oil caps facing up. (If it makes any difference, on this saw the mixture adjustment screws are on the right side, so were facing down.) Tank was (and still is) only about 1/4 full. It started easily, ran fine at both idle and full throttle before I brought it in. It's been in my boiler room, so it's rather warm in there. I did remove and replace the caps a couple of times when I first brought it in, so as not to pressurize the tanks as it warmed up -- just in case. I've not dug into it yet to see where it's coming from, but the area near the right rear corner where the handle bolts on is where the fuel finally made it out of the case.

Any pointers on things I should look for? I'm no chainsaw mechanic, but not afraid to poke around a bit. I'm a bit knocked out from a cold right now, but hope to look at it in more detail tomorrow (Sunday 1/31). Any pointers on known issues or things to look for would be appreciated. THis friend is on a pretty tight budget, so I'm trying to help out where I can.

Check the fuel line. It could have shrunk, to be a loose fit in the hole in the tank.
The seal in the fuel cap could be the culprit too, but not this time, when the saw has been lying on it's right side.

The tank vent.

Thanks, for the pointers, guys. I didn't make any progress today... I'm sick as a dog, and threw my back out as well. I'm not moving much today.

Well, I'm mostly recovered from a bout with pneumonia now... enough that I can take a look at this fuel leak a bit more...

Rocky - is leaking fuel something the tank vent normally does anyway hen stored right side down, or is there something that may need fixing in there. I'll have to figure out where the vent is... I assume it's probably in the upper right end of the tank. Is it possible it just got pressurized from warming up in my basement, squirted out the vent and now it's OK, or might I have blown some sort of seal or check valve?

I do not have any manuals on this, so if someone could point me towards one, or a drawing I can look at, I'd appreciate it.

Slabatnic... I'll poke around with the fuel line a bit and see what it looks like.

Thanks again...

I would start with the fuel line I've replaced a few of these for people that had similar problems, at first look everything was fine after pulling the fuel line from the tank they looked as if a cheese grader were put to them.
