Chainsaw Repair

Got a husqvarna 141 chain saw that i have been having problems with.  The saw will start fairly easily but and run as long as i keep the throttle pulled but as soon as i let off the throttle and pull it again it bogs and dies anyone got any idea what is goin on?

I recently bought a Husqvarna 141LE off eBay and it ran   It had problems similar to what you mention so I replaced the cat muffler with an older non-cat one. I cleaned the carburetor--along with the entire saw---and it ran perfect. As  a matter of fact, it is one of the best running saws I have bought.
It is really a dog with the original set up with carb restrictors and cat muffler

Did you rebuild the carb or at least throw in a diaphragm after carb adjusting didnt work?

thoroughly cleaning and rebuilding the carb should have been done right off the bat. did you check the fuel lines? primer bulb? i've had a few of these and it's older siblings through here with the carb adapter was loose and leaking. also a couple of them with loose engine case bolts. you'd need to remove the rear handle/tank to check those. i highly doubt there is anything major other than a good cleaning and rebuilt of the carb.
