Kinda gives a bit different meaning to, "throwing in the towel! Great idea though. Sounds terrific. So what were the mistakes the PO had made that prevented him from getting the car going? I know there was a lot of while your at stuff which you added on.
I would not call them mistakes. The only thing I found "wrong" was one of the cam oil line banjo bolts, which had the wrong hole size. It is possible the error was made at the factory. What many times happens is that people stretch a restoration over too many years and things have to get redone. For example the brakes on this car were done perhaps 15 or 20 years ago but the car sat unused with brake fluid many years and the caliper pistons rusted. Similarly the fuel in the gas tank decomposed and the tank had to be cleaned and coated. The Webers were all gummed up with old fuel, etc. The best thing is to not let a restoration project linger. If you know something is going to take a long time best not to put any fluids in until the parts is ready to go into service. Ivan
