Hi Netter's, Well, It appears I had spoken too soon. All initial indications pointed to a broken crank on the VW. We pulled the engine down and did not see anything unusual. I took the crank over to a well known machine shop in the area and had it magnafluxed and dye glowed. Zip, zilch, nada.... No cracks anywhere. Now we are at a total loss for any explanation of the vibration. We will recheck the prop for balance but I think it was too severe of vibration for that. Besides, once it was repaired, refinished, and balanced, it ran really smooth.
I apologize for the false info. Now I have no idea what could have caused the problem. Both ignitions were checked with the same results on both. The heads and valves looked fine after disassembly. Carb functioned properly as far as acceleration. I am using a Revflow which has not given me any trouble in 200 hours. If anyone has any ides, I'm listening. We are putting the engine back together and I will fly it until the Corvair is ready. Hopefully whatever the anomaly was, with the rebuild (Again), it will be gone.
