Unlikely, but...

 

I've had this when the bar is getting pinched very slightly when the clutch cover is tightened. Possibly when something is stuck behind the plate that covers the oiler channel, or when there's slightly too much paint applied to the bar around the rails, or if there's any warping in the clutch cover.

 

Basically if the clutch cover/clamping area isn't true or flat.

 

Can be tested by loosening the stud nuts slightly and seeing if the chain runs, then tightening and seeing if it jams. When hot.

 

Fixable by cleaning and/or light flat-filing of the bar side/end.

Take the bar off, put the chain over the nose sprocket and pull it round slowly, is it smooth without riding up and off it.

 

Do the same with the clutch sprocket, can you pull the chain round the sprocket without it riding up and off the gear.

 

Hang the old and new chain off your finger, line up the cutters and make sure they line up over a length of 4-5 cutters - if not, you have the wrong pitch chain.

 

It can't be that hard to sort this one:confused1:

If the bar is 0.063" then the chain is not too wide a gauge, since this is the widest gauge bar.

 

Do you have an old chain, and does it run fine? If so it must be an issue with the new chain.

 

If you don't, and you have the same problem with two bars on the same saw it points to an issue at the bar mount/sprocket end.
