Works perfect.
No need to set , comes pre-set. It worked perfectly from the first pull of my lawn mower. I have a very old craftsman and was having a very hard time finding the right plug. Amazon saved the day. Thank you !!!!!!!!!!!!

Fit, but deceiving picture.
I needed two of these. I should have read the description better because only one came. In my opinion the image should only show one, not four.

fine plugs
Used it for a screenprinting screen exposure unit. They had to be re-gapped but work just fine.
