well it just runs like crap now, i moved the clip to 4th notch from bottom with the washer thing on top of the clip. it smokes alot! like blue 2 stroke smoke but alot, when i rev it up or try to ride it, before it hits the power band it sounds like it hits a rev limiter and it sounds like its "4 stroking" like its very very rich,it takes off like a jet once powerband hits though, it ran better when i had the needle on the 3rd notch, also the plugs are covered in gas, could it be they are fouling instantly from being so rich? or? my airscrew is 2 turns out by the way and i have 280 main jets
