well here is a pic of my plug from today the jetting is close but still not right. when i give it a little throtle it stays reved up for a second then goes back to idle. sorry for the crappy pic its from my camera phone

If it stays rev's after you hit the throttle it's alittle lean on the idle circut...i think

Lean, air leak or the throttle cable/carb slide is hanging up.

it would more then likely be a slide hanging or cable,air leaks usually do not cause a hang after giving gas you will have a ghost rev off of idle if its an air leak.
