Appreciate some input on spark plug reading
Here are two plugs from an engine I’m tuning.
The plug with the shell on is where I started. Way fat.
The plug with the shell off is the last pull yesterday. It’s close but not there yet.
There is probably 8-10 hp left with carb changes but it’s still a bit fat. I could put fuel back in it, but it will lose power.
