Hello, So I am having issues with tight and loose spot with my chain.
The bar, clutch sprocket, and chain are all new.
I notice the difference when I rotate the chain by hand, and as you can see in the pictures below the chain position can be the same (notice the gold links underneath the 'M') and have different tensions.
There is a fair amount of difference in the tension between the two.(The bar nuts had been tightened, so the bar is not moving)
The sprocket and chain are both genuine Husqvarna .325 and the bar is also .325.
Both the chain and bar are also both .063", all bought from my local Husqvarna dealer.
I also rotated the shaft but pulling the pull cord to check the shaft but didn't spot any bend , nor notice any moment in the shaft (not using any calipers, just by eye and holding things next to it as I spin it).
The spur sprocket has some moment as did the previous one approximately 1mm *see photos. Is this normal?
The saw is a Jonsered 2150
I hope I have included enough information
Thank you in advance.
