Hi jbboitnott,
There are 3 things I can think of that would cause that problem. First, the saw was not warmed up enough. Second, did you cut the choke back after your saw warmed up? The third cause would be that your carburetor is not adjusted correctly.
If you did the first two things, then you could try adjusting your carburetor. The carb has to have a richer mixture when it's cold than when it has warmed up. If you have your carburetor set with the mixture too high, it would start but then choke on the extra gas when it was warmed up. Thus, you should lean out the carb.
Huskys carb adjustment screws are on the same side as the oil and gas fill caps. They are above the gas cap. The screw on the left is for leaning the carb, the one on the right is to richen the mixture.
So, turn the left screw, sometimes marked "L", counterclockwise to richen the carb. Adjust a very small amount at a time. Let it run a little, cut some wood, then adjust again, if need be.
I hope this helps. If it does, I'd appreciate your vote. Thanks for visiting fixya.com

hi charlier 421
I think the small holes from the Venturi wall of the carb are clogged.To clean them you need carb disassembly.Near the needle there is a tehnological cover,under the diafragm(fuel pump).Taking off it you will see some small holes maiking conection with Venturi wall.Used ompresed air to clean them.

SOURCE: Poulan chain saw. After starting, chain drive won't move
If equipped, the chain brake may be engaged. Its the lever just ahead of the fore handle. (pull back on it)
If the clutch assy. were frozen, then the chain would move all the time.
Good luck

If I understand your problem the saw starts and accellerates normally but bogs down when making a cut. If true only the "H" needle valve needs adjustment. This is the best explanation and procedure I have found.
