Main is a 180, stock needle,and the slow jet is not stock I think its smaller then stock, anyway I'm having some troubles getting this right, Seems the only way to get this thing to idle right is with the idle adjustment almost at full, and air screw is at almost 2 turns. Now a problem I'm having is when coming off the throttle in any gear it seems to "Surge" a little up and down, not real bad but enough thats its rather anoying. Any thoughts? Thinking it might be rich?
Thanks
