Weimedog,
How long have you had the Husky and has it always been hard to start? The motoplat may have started going south. That will make it real hard to kick start but it might bump start. That was the case with my 74' 250. I replaced it with a with a PVL ignition and it made a huge difference.
Another thing to consider is throttle position. If you don't have much experience with early reed valve 2 strokes, it's possible you may not be giving it enough throttle. I copied the following text from the Northwest Vintage Husqvarna page, tech tips. It refers to a Mag (like mine), but you might want to try it out.
Cold Starting a 250 Mag
Bill Caputo from Sacramento, CA recently sent me copies of Dirt Bike magazine's 11/74 250 Mag test (and bunch of other cool articles/ads- thanks Bill!). As Mag owners, both of us concur that the following paragraph (especially the bold portion) is an absolute revelation:
"Starting the new CR 250 is not easy, even when you know the ritual- which follows. For cold engine starting, flood the Bing until it leaves a puddle on your cases and tweak the throttle while you're flooding it. If you don't lift the carb slide, none of the gas will get inside and you'll kick your brains out for half a day trying to get it running. After flooding, crack the throttle slightly and blast away on the awkwardly located kickstarter. If you work everything just right and jetting and timing are spot-on, it should light off in two kicks. Once its warm, one or two boots should do it. However, every once in a while the SOB will just refuse to fire easily and you'll have a sweaty 15-20 kick hassle. Resist the temptation to richen up the pilot jet for easier starting, for the bike will blubber badly at low rpm if you do so."
Good luck,
Whoops
