I have a 3 year old Husqvarna 460 Rancher that has been awesome, until recently. While out cutting firewood for the fifth time this year, it started bogging down. I was able to finish my work with my little ole Ryobi, thankfully, nobody was around to see me using the green saw when my orange saw was on the ground. I wondered about my fuel, but the Ryobi ran fine on it. So, after I got home, I began replacing parts from a Husqvarna kit. New fuel filter, air filter, spark plug, and primer bulb. I also switched to expensive engineered fuel. It ran fine after that, I even checked it several times. Went out to the forest the next day, and it bogged right away. The altitude difference between my home and the forest is only 1500', maxing out at 4500'. It was still bogging when I got home. Took it to a chainsaw store, but their turn-around time was weeks, not days. Watched some videos on how to take out the carburetor, so I took it out, cleaned it, put it back together, then it ran fine for an hour cutting logs at home. I checked it 2 hours later, and it was bogging. I'm perplexed. Any suggestions are appreciated.

My guess is the carburetor has debris in the pump circuit. I bought three and use them fine until I bought some 372 XP kits. I blew out my carb twice with the same results. New replacements I have seen for $20 to $30. Thanks

I had the same problem with my MS290. For me, I had to remove the limiters on the carb. I richened the high speed jet, adjusted the low and idle appropriately and it was all good.

replace the fuel hoses and fuel filter, they get cracks you can't see and sucks air under load
I replaced the fuel hose that goes to the fuel filter, which I forgot to mention was also replaced. It didn't fix the issue, but a carburetor adjustment got it working pretty good. I went from 1 1/4 turns on the High adjustment, to 2 1/2 turns. It works, but something is still off. I have a new carb arriving today. Thanks again for your suggestions, I'll let you know the outcome soon.

At 2.5 turns out on the H you are compensating for a fault.
Start running a sweepstake and taking bets as to how many more tanks of gas you can run through before it stops for good.
