For what this is worth - I replaced both the original tach and speedo (which was not reading correctly in spite of rebuild by speedometer shop, replacing the speedo cable and "new" transmission) with new units from Speed Hut (GPS speedo - I highly recommend!), and have not seen any of the tach "blip" issues since. Limited miles since, though, so I'll update if this changes.
Interesting. In reading your first post, it seemed like you had slight misfires that would coincide with tach blips, but are you saying that it was tach blips only without misfiring?
It also seemed like your carb balance/tune was nowhere near ideal, so I was hoping this would help. My carbs were well balanced and sorted before this issue cropped up, but it goes to show that these old carb'd engines need regular care and feeding!
