unclepete Posted January 1 Report Share Posted January 1 I am currently setting up Triple Stromberg Carbs on my 6. The Carbs I have sourced from TR8/Stag and Rebuilt/Cleaned. Now I need to connect them together, The Throttle shafts measure 7mm Dia and are Flatted off and threaded but what thread size? It looks like an M7 thread (nearly!). Any Clues would be helpful.

BlueTR3A-5EKT Posted January 1 Report Share Posted January 1 7 mm is a bit big for 1/4” which is 6.4 mm. Perhaps one of the 1/4” sized threads? BSF/BSW/UNF/UNC Quote Link to post Share on other sites

BSF/BSW/UNF/UNC It's some Ba';"rd size! SUs and Strombergs have some dodgy threads sizes and I've asked this question before. I'll contact Burlen (when they open) and hopefully get some answers.....Thanks anyway Peter Quote Link to post Share on other sites
unclepete Posted January 2 Author Report Share Posted January 2 It's official! Burlen came back to me today and at some time during the 70s Zenith/Stromberg went Metric, the thread size is M7......... Thanks for all your input and help as ever Quote Link to post Share on other sites
