Good catches Mike, the carb was serviced at some point since new and the clutch screws were discarded when the accelerator pump was replaced as is unfortunately sometimes the case. The later fuel line support bracket was added as February builds didn't have them. There are other service items in the engine compartment including the distributor vac diaphragm and plug wires. The photo was posted to highlight the carb ink stamp however as is typical in Vintage Certification, there are deductions for these service items, the carb in the main wasn't one of them. I'm really interested in identifying the font for the ink stamp?
