Loose chain?

Check you haven't knocked a clutch spring off somehow during fitting the brake band.

The brakeband has no relation really to the chain spinning when being pulled over.

As above .

Or a problem with the clutch drum needle bearing.

Thanks for the replies, I've checked the clutch bearing and greased it,checked the springs they were seated ok but still turning when I try to start it

Can you rotate the clutch drum ok with the side cover off? It should spin quite easily with no friction from the clutch. If you cant then its clutch related. If you've had it apart you did line up the drum to sit into the oiler plastic disc kit goes back against didn't you and not misalign it.

If the clutch drum has been off, these saws can sometimes spin their clutches off a little on deacceleration and then not mesh with the oiler worm drive when the throttle is applied!

Spud hit the nail on the head with this one, probably needs a new oil pump gear now.

Can't move clutch drum at all!!!removed the clutch and the drums turning the centre boss on the clutch seems slightly low,will have to check it out against a new one.
