fcr

Hi all I've been tinkering with FCR setups for a while and I would like to know what jets are the FCR users using on their carbs. I know it depends on pressure altitude and all that but I would like to have an idea of a starting point to work with. The FCRs have 4 jets, 2 air jets (main and...
