I have a 545 XP Husqvarna chain saw will start and run with finger on trigger but when I take fingger off it will die won't idel
Carb idle mixture and idle speed adjustment might do the trick or it might need a carb stripdown and clean before readjustment. The carb diaphragm can be affected by long immersion in fuel and lose flexibility and in that case replacement is advised.
There is a small chance the vacuum pulse from the engine crankcase isn't strong enough to keep the carb supplied with fuel at low rpm.
This isn't unusual and usually happens when a 2-stroke engine has been idle for a while, such as over winter. It was running fine last season but now it simply won't behave.
In that scenario it is possible the crankshaft seals have lost flexibility and air is being drawn past them reducing crankcase vacuum...

Why won't my 130BT blower start? the unit won't start replaced the plug, dumped the fuel added 50:1 gasoline still nothing? Sprayed starter fluid in carb still nothing.
I had that same problem. I have not tried fixing lately. Take apart the carburetor and spray it and brush with carb-cleaner. You can try cleaning the fuel filter in the gas tank. Fish it out with your finger or a piece of metal wire. Take it apart and clean it with gasoline, also clean the air filter with soap and water and let it dry. If it still does not start, clean the muffler, where it emits the burnt co2, carbon builds up there over time (there is also a screen there where you can see the brown/black carbon). Try cleaning w the Carburetor cleaner spray and a toothbrush, wire brush or thin flat-head screwdriver and let dry. If that doesn't work, maybe you need to replace the whole muffler part. I think that is what I might do. I'm not using so haven't got around to fixing it. Hope it helps if not maybe a professional can help. Good luck...
