06specialedition Posted April 5, 2010 Report Posted April 5, 2010 Do a plug chop. You prob need to move your needle and adjust your air screws...but i'm no expert, just thought i'd give you a suggestion Quote
moparken426 Posted April 5, 2010 Author Report Posted April 5, 2010 the air screws are all the way out for it to run Quote
moparken426 Posted April 5, 2010 Author Report Posted April 5, 2010 the air screws are all the way out for it to run so what it is telling me i need 340 mains and 30 pilots seems like a big jump from 260 and 25 but i will try it Quote
06specialedition Posted April 5, 2010 Report Posted April 5, 2010 You main jets control your WIDE OPEN THROTTLE.....so if the bog or hesitation is in the 1/4 throttle its something else. I run a 320 main but I'm at 5,000 feet above sea level. Quote
