Simple question and looking at Norman Nocks "Tech Tips" I got from him 7 years ago - when you pull on your choke cable the carb jets should lower to enrich the mixture, correct ? While tuning my carbs noticed that the choke cable does speed up the engine but barely moves the jets when fully extended as now adjusted with the metal stirrup that hooks up both SU's. To work properly the stirrup should be adjusted so the jets lower, right ??? Know this seems like an obvious question but I usually try to practice "if it aint broke, don't fix it" and really have had no problems starting the Healey. But, if I need to do the above I can easily fix it while I have the cold air box off.
