I sometimes for fun, search the "parts and accessories" section on ebay for: 5200,the (Holley-Weber number). Lots of these carbs and parts turn up, most are used and abused and the new/rebuilt ones are much more expensive that from Tom. I adapted mine to manual choke, helps alot and no extra plumbing needed. Manual choke kits are available at just about every discount auto parts store anywhere.
