I am having a hard time setting up the needles I have the H speed at 4 turns out for it to run I get 6100 rpm with a Menz 24 10 Low speed set at 2 turns out. The problem is when I hold the throttle at 50% it wants to quit.I try to lean both needle and it gets worse I richen it and it stays the same. I am using the oil that it came with at 32 to 1. At first I had a bisson pitts muffler then I swithched to a slimeline modified da 50 pitts . I have tried the factory settings and it would not run. I have in a wildhare 28% 540 edge.I have replaced fuel,fuel tank,fuel lines fuel filters I tried amsoil at 32to 1. I don't know what else to try.Thanks in advance
