i am just about to check valve timing on my 510 husqvarna with a vernier. when i set the standard timing the cam sprocket bolts do not line up as they should IE front bolt is low back bolt is high if i move by one tooth it is visa versa. i think this is a common problem. if it is out can i file holes in sprocket so the cam timing lines up and then peg the sprocket to cam so it does not move
if the cam timing is out by 1 deg how much power is lost?

Are you using a degree wheel? If not, it will be hard to get an accurate reading especially with a vernier caliper. It's best to use a dial indicator and a degree wheel imo.

Do you mean one degree or one tooth? One degree won't make much difference. It may even increase power depending upon how the engine was set-up from the factory. One tooth will make a big difference.

Are you sure your cam chain is not excessively worn?
