Hi, I have an Husqvarna 41 chainsaw, it has been brilliant all these years but just recently, for no aparent reason it stopped running when I put it under load. I have stripped it down to clean it and have had no success? I believe it to be a starvation problem. I do not know where the breather is on the gas/petrol tank! Please advise?

2 things you might want to look at.
1) Vacuum test your fuel line. This is a common problem with huskys.

2) Check to see if the exhaust port or spark arrestor screen is plugged up. If so pick out a carbon deposits.

40 to 1 is the ratio.

I too have a rancher 55 and had what sounds like the same problem this week. It would start fine but run for only a few seconds at a time. I took it all apart today and found the problem - a cracked fuel line. In the places where I could see the hose it looked fine, but it wasn't until I removed the fuel tank that I found the crack...right where it exits the tank and then goes thru the housing above it. You don't need to remove the tank to replace the hose but it is easier that way. You do have to push it thru a grommet at the top of the tank. I read some other posts about checking the tank vent to see that it's not plugged up. Mine was ok so I knew it had to be something else. The vent is in a hole about the size of a pencil and is recessed about an inch into the tank on the upper right side. Its partially covered by a plastic cap that's part of the vibration damper, which can be removed to gain access to the vent. The vent tube can then be pushed out from inside the tank with the use of long needle nose pliers, but be gentle. I just loosened it then pushed it out with a finger. I put it all back together with a new hose and its running like new again!

Here you go. If the price seems high there are likely several more to be found on this page. Good luck with it.

That seems low to me. Page 15 in your manual is the only oil discussion I found. Usually there is an oil pump adjustment reference somewhere. I didn't see one beyond return it for service on page 15. Are the chain and bar hot after cutting a while? I recommend you not get a longer bar without an oiler adjustment. I think the hand of the EPA has been here.

An IPL (exploded parts list) for a 440 can be found here:

There is no oiler adjuster listed. HTH

Might be a good idea to copy the IPL,
