moving from 15 to 30%

Any advice? I'm ready for some more power.

Make sure you richen the mixture. It might not be a bad idea to do another break-in period.

There's no such thing as a "re break in" unless you change the ring or sleeve :)

Richen the needle atleast a half turn or so and tune from there. Better too rich than too lean.

thanks!

Try about 3 clicks richer. No break-in necessary.

Have an extra glow plug handy - changing fuels can lead to glow plug failure - other than that and the suggested richening of your mixture you should be good to go.
