Just got my husky rancher today, assembled it, tensioned the chain then pulled the chain round by hand and its tension is not consistant? Tight in in places, then in others really slack any ideas as to my problem?

Mismatch between sprocket and chain, or chain not properly on sprocket, is most likely - but worst case it is a bent crank.....
Only just taken it out of the box, tight against the bar one minute then rotate it and its sagging freely. Using the chain that came with the saw. Ill try the other chain I bought tomorrow hopefully it is better. Damn thing almost jumped off the bar, scared the hell out of me thats for sure. Dangerous things these chainsaws not starting it again untill im sure its good!
I'm having the same problem with a new saw. I've replaced the bar, chain and sprocket. I considered a bent crank but I'm not sure that would manifest itself when pulling the chain around the bar by hand since the crank isn't turning. If the crank was bent I would think the chain would either be loose or tight when turning by hand. .....
A worn sprocket straight out of the box? i hope not!
You likely have a burr on a driver, maybe it is bent some. The way to fix it is run the saw. If you feel comfortable doing so, loosen the bar nuts enough to adjust the chain, start the saw and rev it adjusting as needed. once you have achieved proper tension tighten the nuts with the bar tip held up of course and forget about the problem. Throwing chains often causes this problem, a lot of the time the chain won't even turn. So a guy loosens the chain and wears the burr down by spinning the chain loose. tighten it back up and carry on.
If the drive links are deformed, let me suggest that you NOT do that. Rather, use whatever large hammer you have with a flat face as an anvil, and peen the drive links flat with a small hammer. Your suggestion is abusive to b&c.
Adjusting chain with engine running seems a good way to amputate something.
