    I have a 1999 Husqvarna rancher 55 that started having problems last summer (June 08) The wife noticed gas fumes in the garage (where I store the saw) after I finished cutting some wood (I am guessing I went through a tank or two). At the time, I didn’t make any connection between the fumes and the chain saw because the saw ran okay.

    The next time I used the saw (about a month later) it didn’t seem to work as well at high end (bogging down/missing?). I replaced the spark plug (CJ7Y) and everything worked fine (several tanks of fuel), however, the wife still complained of gas fumes in the garage. This time I noticed some fuel under the saw, so I placed the saw into the shed but still didn’t think anything of it because it was running fine.

    The next time I used the saw was about a month ago. As usual it started in 3 pulls and idled fine. However, I couldn’t get any power out of it and it would run at full throttle for a couple of seconds before it started coughing. I figured it was bad fuel or a leak in the line so I replaced the fuel, fuel filter, fuel line, and spark plug with no luck.

    I took the saw to the local home and garden store that sells and repairs Husqvarnas. After two weeks, they provided me with a $45 bill saying that I had the wrong spark plug (They were the ones that sold me the CJ7Y referred to above) and adjusted the carburetor. As soon as I took my saw out of my vehicle, I knew it wasn’t fixed as there was fuel leakage on the cardboard that I placed the saw on. This time the saw was rough starting (7+ pulls to get it started). After it started, it ran fine for about 5 minutes then it went back to the low power/coughing at full throttle. I was able to do some cutting but it was very slow. I tried opening the fuel cap while cutting (and it seemed to help a little). One point I would like to mention is that the saw seemed to work fine when I was cutting a stump.

    I then replaced the fuel cap and fuel vent and still no luck. That is when I noticed fuel leaking from the vent. I removed the vent and put the vent filter in the other way to no avail. It appears as though the fuel is leaking through or around the vent. When I rotate the saw 90 degrees in each direction, fuel drips from the vent and bubbles are visible. There is pressure in the tank as when I open the cap, the fuel is squirted out. I do not have any pressure gauges and will not take it back to the $45 spark plug guy.

    I think it is the tank ($120) or the carburetor ($45) not much else left. Any help would be greatly appreciated.

    Thanks,

    John

    Sounds like a bad fuel hose to me

    Thanks for the feedback but I already replaced the fuel hose and fuel tank bushing, do you think I might have torn the hose? I don't think that I would still get the gas/air pressure releasing from the gas cap after I shake up the saw if I had a leak in the hose would I?

    When did you replace the hose? Some hose material only lasts a few seasons now with the new ethonal in gas...., Also, check the area where you seated the line. Good Luck...

    I replaced the hose last weekend along with the fuel tank bushing.

    Any suggestions is appreciated.
