I got my arrow motor broken in and then my rt carb arrived. It came wiht a 70 68 66 and 64 jet. im running a 32:1 fuel/oil ratio. The 70 jet ran awful, couldnt use full throttle at all. The 66 jet runs, but its got that "cold naturedness" that i really didnt have much of with the NT carb. Of course this carb runs at low speeds a lot more smoothly but with the nt there was no power then it all seemed to come out at about 20 all the way up to 30. this it is pretty flat and then chokes out at 23 until it warms up, it doesnt rocket up to 30 anymore. Am i doing something wrong?
