I get this wierd bucking around 2800rpm. Notice the Lead/Trail timing numbers that I have outlined in red. The numbers start getting spuratic. I have new plugs, wires, cas is set and timing on the money. No leaks, went through 3 cans of carb cleaner without any findings. I had redone my grounds a while back. Maybe a ground problem? I had just installed a Crane hi-6 hoping it would solve the problem. Nope, but my idle is solid now. Any help appreciated. My mods are in my sig.
