If yer gonna buy one, sullivan dynatron. Had no trouble starting my ryobi with a garden tractor battery.
You might want to rebuild that carb. If the diaphram is stiff it''ll be tough to start. I dont know about huskies but on ryobi''s, a good starting point for the needles is 1 1/2 turns. Might not be a bad idea to mount it on a stand for easy access.
