Spark Plug Opinions

I will do that when the carb comes in and gets installed.

NGK plugs are my favorite. Then comes Champion, Bosch, and others. At the bottom of the list for quality and reliability are the cheap Chinese “Torch” spark plugs and knockoffs.

I usually immediately change out anything with a Torch in it.

Update: The carb is on. One minor adjustment and immediate startup cold. It runs good, but I will change the plugs tomorrow and get a new baseline.
