Check the gap!
Plugs work great. I will say for those reviews saying they got a dud. CHECK THE GAP!!! Both plugs were not at 0.030 as advertised. I gapped the plug and it worked perfectly.

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
