750 E85 Ultra XP 0-80843HBX original calibration. How do I find all the original calibration information? I'm talking about everything (jets, air bleeds, IFRs, PVCRs & Emulsion bleeds). I purchased a very clean used carb. I know they changed the jets & squirter. I found a little brass dust in the primary emulsion passages and I just want to make sure no one changed the sizes of any bleeds or restrictors. Any information appreciated. Thanks.
