that sucks, I remember with the '72 standard I have now, I drove to Washington state, 8000 miles a few weeks after it got rebuilt. It drove perfect there and back, then a week or two after I got back it was a cold morning, I went out to start it up and it spun a bearing. pulled it apart, rebuilt it. Me and my friend thought it was just debre in the oil. because of the marks on the bearing that spun. so we put a oil pump with a filter on it, then less than a week later it spun the same bearing. so we pulled it apart Again and aline bored it, it's been working perfect ever since.
Sometimes it just takes a few times to get it right. The thing is, don't give up. :righton:
