I have beads in the wheels and that vibration occurs once I'm rolling at about 35-40mph and is gone in short order. This starts the moment I press on the gas. Its a fast vibration, so it maybe engine related. Its a smooth vibration, not sharp. It disappears once I get rolling and the engine RPM is above 2000.
My engine always seems to run rough when I rev the engine from idle, so it maybe related to that.
To try to cure that I have changed the coil and pickup to be sure I have proper phased ones (from DickP), new distributor cap, new rotor, new module, 2 sets of spark plugs (AC #7 and now NKG), 2 sets of DickP's plug wires (I pulled the spark plug connector off the wire on a couple trying to remove the wire from the plug)
One time I tried shorting out each plug in turn by removing the plug wires from the cap and looping a small copper wire around the terminal, then replacing the wires on the cap. I was able to cut the spark to each cylinder, but I was not able to determine that any one cylinder was the cause, they were all firing. I gave up thinking it was just the nature of the beast
We are taking it to the family cottage about 30 miles away today, so I'll try to pay more attention to symptoms.
