Bought my DTR few month back was lacking power in first and second gear, looked at the carb and it had seen better days so I decided to clean it. Put it back together and it ran the same. It came with a dep pipe so after some research decided to rebuild it with the suggested parts for the dep pipe. Put a 5DP39 needle in, 22.5 pilot jet and 260 main. Started with needle clip on the second from the top and it started well and idled okay but bogs and dies as soon as you put revs on. Since moved the clip to position 3 and 4 and still the same although slightly better. Runs and doesn’t bog with choke on. Another thing is the air screw is making no difference to idle no matter how far out I turn it even though I’ve just replaced that as well. Any help is appreciated TIA
