I have the same problem, EXACTLY!! Same year, same can, Dynojet stage I, and K&N. I put the e-clips on the third notch....where are yours? I have to rev mine to 25-3k or it will take a $hit. I notice some black smoke. It's running rich on the lower rpm which is controlled by the needle jets. I originally had them on the 2nd notch, but it sputtered badly and lacked oooommph. When I went down a notch, it's too rich. I know they make half step spacers that go inide the diaphram but I don't think a half step would make that big of a difference. Am I wrong?? Also, does anyone think synchin' the carbs would help?? Thanx folks. :bowdown: :hammer:
