Thanks for the info, DFeeney. I had heard the vacuum tank had been replaced, by someone else, but didn't know about the carb. This carb was recently rebuilt, by the PO, who said even after the rebuild, he couldn't get it to run other than at high idle. My dad has tried to start it and it turns freely and there is spark, although he commented it was "weak", but he said it wouldn't even start on Ether. I'm a bit worried we are going to be into this car a lot more than he wanted to be.
