I just bought a fox 4.2 to go on my giant stinger.the motor seemed to be to rich i did not want to mess with it cause it is bran new i was going to lean the top end and bottom end by a quarter of a turn what is the lowest you should go from base.if the needle were all the way in what would be the least turns out you would want to run it.before i could adjust the motor the firewall on the stinger broke what a _ _ _ _ drag please help
