Didn’t work well in my B&S engine
Worked for 15 minutes. Repeatedly stalled. Replaced with name brand and ran like new.
UPDATE. Seller immediately offered refund well outside refund window of opportunity. That’s nice to have someone stand behind their product

Original OEM equipment
They seem to be the copper plug required for this engine. Runs great and as it should.
