To fix the slow leak from the jet assembly on my 1959 TR-3A I decided to give the Superdry Jet Bearing and Seal kit from Moss a try. With the carbs pulled I noticed that the return spring on the throttle spindle on the rear carb was not under any tension. As a result, that spindle was free to float a bit. With the spindle connecting rod fixed in place both of the throttle discs were fully closed. That suggests to me that only the front return spring is under tension at low throttle settings with the rear spring coming into play at the higher throttle settings.
So, here's my question. Is the rear return spring supposed to be under tension with the throttle disc fully closed? If not, is there any guidance how to set the tension on these springs? I have not been able to find any discussion of this in the manuals or online.
