I've got about 3/4 a gallon of fuel thru my savage. I decided to return the needles to factory and re-tune it up. I've got the high and low speed needles down to about 3 turns. Runs good good like that....hits second nice. BUT....the thing will not idle worth anything. The idle screw looks to be adjusted correctly...it always has a 2mm gap in it. If i let it idle for about 5 seconds it dies. I'm running blue thunder 20% in it. I'm thinking maybe it too rich or something because if i put it on a box and run it there ends up being a big pile of oil from the exhaust on the box in a matter of 2 minutes? Anyone have the same problem or any advice to try and follow?

Thanks in advance!
