I have a new EK-4 also and besides what the others have allready said you should consider richening the low speed needle you could also check out the midnight madness site if you haven't allready. I talked to Thunder Tiger last week and they told me the high speed needle should be around 3 turns out the mid range needle flush with the case and the low speed needle 1/4 to 1/2 half turn in from flush. But these settings are a starting point and only for the new model with the tall head. If you have the low speed to lean it really raises the idle. If I can help any more private post me as I have nine differant trucks and a lot of experience tuning. Here's the Mid-Mad link.
