re-building TR6 Strombergs

[jbonina@nectech.com]

     My mechanic attributes my TR's hesitation to among other things, worn 
     carbs. He's replacing a rubber diaphragm (?) in the carbs in hopes of 
     eliminating/minimizing this hesitation but he suggests a complete 
     re-build.
     
     It sounds like more than you would do with a carb re-build kit; 
     probably involves machining and re-bushing,etc.. 
     
     I'm accepting suggestions, references of carb companies (especially 
     from those with pleasant first-hand experiences), expected costs, etc.
     
     Thanks in advance to all.
