runs great and purrs like a kitten except for this little cut-out around whatever this rpm is that it does this and the fact that I cannot get a tach to work on it.
I'm no expert, but it sounds ignition related to me, especially since it's only happening at a particular RPM. I'm wondering if you could be getting electrical interference (noise) from somewhere? Were there any electronics running onboard? What kind of spark plugs are you using?
