Ok so do you remember when sycro your carb's with vacuum guages and how the needles used to shake real bad? Forget trying to get em to sync'.....well these little jewels are what stabilizes the vacuum 'Pull' eliminating the shake, surge, flutter you get it right? Put these in the hookup line to the carb's and 'Walah!' calm vacuum 'Pull' allowing you to accurately adjust all the carb's to each other. Keep a spare cuz your buddies are gonna want a set.....NO BS folks.
