Spark Plug Advice Needed
Just an update on the tuning of my engine.
The spark plugs were changed one heat range hotter.
I replaced the metering rods with rods that are 8% leaner in cruise and power modes. It developed a lean bog just before the secondary opened.
So I replaced the orange step up springs with pink springs and the bog disappeared.
The full throttle jetting still has to be checked yet. There is only 20 miles on this plug but it looks better.
