The saga of trying to get my 47 running well continues.... When driving the car there is a vibration starting at about 90 km/h. I thought it was a drive shaft angles problem, but I’m not sure now. When I rev the engine in neutral to 1800 rpm there is a noticeable vibration. 1800 is about where the engine runs at 90 km/h.
So far I have run the engine with the water pump, alternator etc disconnected and the vibration is still there. The engine was balanced (maybe not done correctly?) when rebuilt. So my question is; where should I look for the vibration cause before hauling the engine out and getting it rebalanced. I’m hoping it’s something else that is more easily addressed. Any ideas would be greatly appreciated.
