been watching a few youtube video's re. breakin procedures and figure i'll put 6 full tanks through the engine at this setting, or while it remains hot, then start slowly leaning it out.
from what i understand it's going to take the whole gallon of fuel before it's even close to run in, so there is no huge hurry to start leaning it out.
Start to Lean it out as you go just a little at a time and you should have it tuned and ready to run by the 1 gallon mark. Most Axe Rossi will be ready to run Hard after the first Gallon and ready to race.
