I have a Husqvarna 359 saw which I purchased online about 3 years ago. As for use, I am just about through the first chain.
The last two times that I have used the saw I noticed that after about 5 minutes of running the motor would not stay running at a low speed. Say something less then 50% throttle. To get it started required choking at about 50%.
Below is what I have done to date.
The last time I used it I checked the jet settings and adjusted the high speed to its max open, to no avail.
Stopping the saw for 5 to 10 minutes restores it to a normal state. It will start up and idle.
I started out to remove the carburetor until I figured out it appeared to be a major effort. I did remove the top cover to the pumping diaphragm and every thing looked good there. Same for the fuel hose in the tank, looks good. But still the same problem. Saw runs strong for the first few minutes.
Having thought this through a bit more it would appear to me that its a fuel delivery problem. Which for me means a diaphragm, hose or seal on the crank case. But again I was after a quick fix looking for debris in the carburetor jets, and still would be if I can figure an easy way to remove it, just because its easy to do compare to the rest.

Re: Husqvarna 359 Low speed running
A lot of 2 cycle engines do not run very well if they have been put up for a long period, (say for winter) with gas in the engine and carb. I finally learned the hard way that if you empty the gas tank and start the normal way and use up the fuel in the lines and carb, you don't get the residue build up from gas that has deteriorated over time. Suggestion: empty the fuel out of the tank and run it dry by starting. g\ Get some gas stabilizer and add to fresh gas, fill the tank and run a few times. It will take awhile but you can gradually get rid of any residue build up
Hope this helps. Loringh ps Please leave a rating if appropriate Thanks
Read a number of posts on arborsite that this problem likely stems from the clamp holding on the carburetor. Clamp is plastic and stretches over time causing a air leak, Understand they recalled this part and have replaced with a more traditional metal clamp.
Check your in tank filter. There could be debris in the tank. Running for 5 to 10 min. could draw the debris to the filter and clogging it and letting it sit for a little while could let the debris settle. Just a thought.

359. ... Husqvarna chainsaw fuel line check and replace. mweba1. SubscribeSubscribed .... You will want to inspect the tank vent and fuel line.
The carb is an "all position" type and shouldn't be the problem.
Check and clean/replace the fuel filter in the tank. Dirty or old gas, sawdust and/or water etc. settle on the bottom of the tank; and when the saw is turned over will plug the filter, causing the symptoms you discribe.
It is possible, if you used old gas(3 to 6 months) that small varnish particles have gotten through the fuel filter and have pluged the fine screen in the carb(located under the diaphram).
Ask to see the sales receipt if you are in need of proof of purchase date. Even contacting Husqvarna to ask when it was registered may not be the actual purchase date. I saw a question not long ago about a saw that was purchased new that had been out of production for a couple of years. It is possible it sat on a dealer's shelf for a period.
Looking at the serial, it was manufactured in 1998, the 51st week (Dec), and was the 4th product that week.

My Husky 359 workshop manual says on Appendix A (USA) says "H" 3/4 turn CCW from lightly seated. "L" 1.5 turns CCW from lightly seated. Page 36 (every other nation on earth) 1 turn CCW from lightly seated for both the "H & L" needles. There is no recommended initial "T" setting. (from manual) "The idling speed is correctly set when the engine runs smoothly in all positions and there is a clear margin to the speed at which the chain starts to move". I wager your manual would be similar. These are initial settings and the saw needs to be adjusted for performance. Start with a clean air filter and a fresh fuel mix @ 50:1 per Husky (1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil).
This explains performance carburetor adjustment better than I can: Carburetor Adjustment by Madsens.com http://www.madsens1.com/saw%20carb%20tune.htm CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly. Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run. There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too. I hope you found this post helpful. Lou
You can find both an Operator's Manual and an Illustrated Parts List for your saw here: HusqvarnaUSA.com http://www.husqvarna.com/us/homeowner/support/download-manuals/ Enter the 3 digit model number (no XPs, Es, just the numbers) Serial number decode – for use with IPL 06 1500198 06 = year produced – 2006 (single digit before 2000) 15 = week produced - March 00198 = 198th unit Husky produced that week
Take your saw with you and stop by a local saw shop (regardless of brand). Odds are good they have the correct scrench and it will cost the same without the shipping charges.
What you describe is common in many chainsaws. Try loosening then reseating the oil cap before putting her away to relieve any pressure built up in the oil tank. Check all the hose connections. HusqvarnaUSA.com http://www.husqvarna.com/us/homeowner/support/download-manuals/ Enter the 3 digit model number of you saw; uncheck "Manuals"; Check “Illustrated parts lists ”; then search. Serial number breakdown: 06 1500198 (Husqvarna 359) 06 = year produced (prior to 2000 there is no space and only the first digit is used (61500198 could be 86 or 96)) 15 = week in 2006 it was produced (March) 00198 = 198th unit produced that week regardless of model or type
This saw needs aproxamitly 150 psi. Any less than 120 and you will have problems with the saw breaking up at high rpm and stalling under load. Pop the muffler off and take a peek at the piston and the cylinder walls for scoring. If its scored it will need a new jug and piston, the kit from Husqvarna, includes everything you will need, should run from $175.00 to $200.00.

Or you can email me at firstname.lastname@example.org Hope this helps, feel free to email me with any other questions, we are a Husqvarna dealer/repair center and can help you out with that saw. It is a great saw all the features of the XP line at a fraction of the cost. It has the 3 piece crank and magnesium case. It is definitely worth putting the money into this saw! -Steve
