No. But what I would do is remove the vacuum diaphragm entirely and while it's off blow compressed air through the signal taps so you know they're nice and clear -- maybe even run a thin wire through them. Then confirm your linkage is not bent or jammed and then replace your diaphragm with the Quick Fuel Adjustable Vacuum Secondary. I know it works and it's really easy to adjust. $38 at Amazon: https://www.amazon.com/Quick-Fuel-Te.../dp/B00ZCQ18R6
EDIT -- And you do not need to remove the carb to install it. Just watch the circlip and the little gasket and don't drop them down in the engine somewhere.
