Welcome to the wonderful world of defective brand new parts sold via the criminal network called Amazon.
Now Bezos wants your hard earned money in ever increasing amounts so go and buy a more expensive one, 3 . 4 , 5 , 6 , 7, 8, 9, 10 times .
Eventually you will get a good one, but don't hold your breath.
So you have a couple alternatives
If buying mower parts from a real mower shop parts supplier (bricks & mortar or on line ) where you will get quality assured parts that will work properly is against your religion then buy from Alibaba where 99.999999% of everything is at least of merchantable quality and not defective parts sold using the description as OEM (omitting the QC reject ) .
And no before you ask I am not a franchised retail outlet or Alibaba vendor.
I rarely have any problem with the Rotary, Stens, Prime Line or Oregon parts I get from my wholesalers but my workshop is full of equipment that the owners tried to fix using junk they bought off ebay or amazon.
Your money
your choice
