My Husky 365 that dies when you point it nose down in about 2 seconds.
Craftsman 55cc that starts well, idles well, no change in RPM'S with saw in any position.
I know, needs pressure/vac test but does this symptom seem to indicate anything particular to anyone?
Cuts good 1st cut, 2nd cut boggs a little and by 3rd cut tries to die unless you give it 30 seconds then rinse and repeat. Runs great WOT?
Low side jet clogged?

For the Craftsman, could be a tank venting issue too. Also, the fuel line could have a leak in it. Same with the impulse line if that saw has one. Finally..........the pump side diaphragm in the carb could be going out and/or there could be crap (water, sawdust, etc) on the screen in the carb.
