If you are trying to go lower on idle and wont run steady...you will also need to adjust your low needle - prob need to lean it out.

How many turns out from the stock setting for the low end are you running? Stock setting is flush with the plastic control arm correct? I have mine about 2.5-3 full turns in and still runs bad on the low end, but transitions to high end real well. I have had about a gallon and a half through it, but the low end is still 2500 rpm or more, anything less and it does. I am running 15% fuel and an OS F plug. Thoughts?
