Right now I will be happy if I can get it to run for more then 15 seconds.

Steve,
As you say a private owner fitted the carb, check it is a 40NNIP and not a 48NNIP. The 48 was for some B81 engines, also the 40NNIP was fitted to 8 cyl engines of certain Marks and jetting would vary between 6 and 8 cylinder engines. If the wrong carb was fitted, this could be the problem.

If you can, make a note of any numbers on the carb and around the base flange (if any) and post them on here.
