HELP--Strange Vibration in engine!!!
I just spent over $1600 to have my original 240 rebuilt. I seem to have some sort of vibration that is kind of there at idle, but increases with the raising of the RPM's.
It seemed like a spark knock or a fouled out plug, so I replaced the plugs, wires, cap, rotor, points, and condenser. It seemed to help a little, but it is still there.
Could it be the dwell setting???
Please HELP!!!

How many miles do you have on the engine since it was rebuilt?
this symptom does sort of sound like a dead cylinder. to test for spark problems just unplugg one spark plug wire at a time and run the engine. you should be able to notice a rougher run than before. if one of the wires doesn't make a difference then there is the prob.
I would do a compression check to make sure all the cylinders are doing their job.

I have a very bad drone type of vibration that harmonizes too...on my '79 300. I know my engine is due for a rebuild, but I suspect the vibration to be either from a failing balancer or worn main bearings. How well was your engine balanced during the rebuild? I'd seriously question the party that rebuilt your motor.
