360 engine vibration

Standard plugs I think, I have had 2 different sets in NGK I recall. I do have a 3rd set autolite I'm going to try. Gapped 35 thou.

Also new plugs leads,, dizzy cap, rotor arm, reluctor, coil pickup, coil,

Carb has been stripped rebuilt twice and ultrasonic cleaned

But I will revisit all of above. Thanks for feedback.
