When I bought my car there was a carb like the one you have on it. Manufacturer name stamped on the body was Holley. I thought I had seen all Holley models but I had never seen a Holley that looked like that. It ran like ran like crap so I figured I would clean it up and possibly repair it. I took it apart, cleaned it, and tried to put it back together but the little parts in the accelerator pump were to hard to assemble and some broke. I threw it in the trash and bought a Chinese copy of a Carter BBD two barrel off eBay for $80. The Carter BBD is the factory installed carb for the 273. The Chinese copy body casting and every thing else looked great when it arrived but upon installation it barley worked. The accelerator pump spring was way to heavy. I had to use three springs to get an idle. It kept flooding and ran terrible. I tore it apart and found it hadn't had any adjustments made at all. The throttle plates didn't even close. The throttle shaft was sloppy and sucking air. They had just slapped it together. A lighter accelerator pump spring was found at Ace Hardware, of all places, and I made all the proper adjustments to the float and other parts. I went Elderly Auto, in West Linn, Or, and bought a BBD core that had a tight throttle shaft and replaced the Chinese throttle body. The car now works fine. As for a picture of the carb, the repair manual has them.
