Hi Folks, new to this forum, ran my new DL50 the first time today. I am not sure what is happening, but I had to open low speed needle (factory setting was 1-1/2) to get the idle down to 2500 rpms. The butterfly is all the way closed, or at least it appears to be (pushing on the throttle arm) all the way closed. The LS needle is now open to about 2 turns. The engine gets down to 2500 but is very rough running. I have been searching this thread and have given up. BTW, the beast started the first time in about 8 flips of the prop. Wonderfulllllllllll. Thanks in advance to all. Bpar
