Can anyone help me find a good starting point for the length of the metering jet and how many turns out on the power jet? I have a 68mm cheetah cub, 4 mil hot rod crank, 115mm long rods, msd coil, v-force 3 reeds and 40mm letron alcohol carbs. The current problem is that it is blowing fuel out of the pipes, which are Shear custom out of from drag pipes on the left side. Any information would be appreciated!
