Default Re: New Build 66cc Engine is slow and will not idle at all

if dropping the needle doesn't get you to a place where it will idle until it runs in a bit and can then be raised some, then look for seepage along the seams of the cases - you may be leaking there a bit or maybe a seal is leaking - tighten all case screws with an impact driver to seal the cases (don't forget the three screws under the clutch)
