Service & Maintenance Question
We got this 460 Rancher over a year ago. Then it sat in the box 'cause our tasks/priorities changed.
Took it out of box added oil and fresh mixed gas about 2 weeks ago. Got it started, but it would not run right. Would only run with choke on. When choke pushed in it died. Then throttle trigger pulled it died. Messed with it about 1/2 hr then quit.
Took it to authorized dealer 1st of week. When I got home dealer had called - I called back. Was told they could not find a problem - tech went to shop while I was on phone and started saw. It sounded like it ran fine.
I went back to dealer this AM to p/u saw. I started the saw at the shop and it did run great. So I get saw home, use the saw about 1/2 hr. Run gas out and refill gas/oil.
Then the same problem re-happens! Will start after I push fuel bulb, will run a few seconds or minutes. But never more than 1 to 2 minutes.
The same gas has always been in the saw so I have about eliminated the gas being bad as the problem. I have not made any carb adjustments. The saw will start without a lot of problem. The fuel bulb has some gas in it almost every time I have looked at it.
Now a theory-- it seems like the engine is not getting fuel. Could the fact the saw sat in the box over a year with the gas tank top on tight from the factory be causing a problem? Could the tank vent be not allowing air in the tank?
The reason I asked the question is I had a gas powered portable generator in a shop recently and that proved to be a good bit of the problem with that engine.
Right now I am very disappointed in this saw. After making the decision to go for the "top of the line" saw and spending a lot more money than I have been spending of previous saws I have a saw that I can not use.
Thank you for taking the time to wade thru my tale of woe.
Any comments or suggestions regarding a solution will be appreciated and considered.

Answer
Jim,
It sounds like from your description that you have a carburator problem, I am not sure why if it just sat in the box un-used that it wouldn't start. When its boxed up, it should be able to sit for a long time, years and years and still be able to start, provided there is no fuel inside of it. However, If fuel was in the chainsaw when it was in the box, or fuel was in the carburator and allowed to evaporate. Then its possible that the dried up fuel is causing the problem..
Second sentence of taking to the dealer and getting it running, I am guessing that the dealer probably did not take the carburator apart, and clean out the inside of the carburator, but put additional fresh fuel into the tank, they may have also used a product called "Sefoam" in the gas which loosens up some of the dried fuel. He was then able to get it started again, but there was probably still some gunk inside the carburator, and after it sat and before you tried starting, It settled out inside the carburator blocking one of the jets or passageways inside the carburator, and again it wouldn't start.
My suggestion would be to get the carburator cleaned and adjusted at a Husqvarna repair center, then when you let your saw sit for a period of time, run all the gas out of it until the saw stops on its own, give it a few more pulls with the cord, and make sure the fuel tank and primer bulb are empty of all gas. Then remove the spark plug, and put a teaspoon or so of engine oil in the cylinder, and put the spark plug back in, then let it sit in storage.
For shorter terms of use like every three months or so, I add a product called "Stabil" which is a stabilizer added to the gas and engine oil, but the best solution is obviously fresh gas and engine oil to the correct ratio.
Another possible solution, is run a small amount of "Sefoam" product mixed with your gas and oil periodically to dissolve any evaporated gas or resin inside your carburator, you only need a cap full to a tank of chainsaw fuel, and the product is available at most automotive stores.
I hope this helps!
