Renewing as many parts of the carburettor internal & external components as possible will help avoid the frustration of difficult tuning, weeping fuel, and overall poor running.
Consider having the internal parts, that have not been renewed, sonically cleaned, and perhaps the external carb bodies vapor blasting (taking care to remove any abrasive media before assembling). This will help restore the carbs mechanically and cosmetically.
Here are some other ideas for the external linkages and other damage and corrosion parts:
Add as many new parts to the same shopping cart as you wish, new joint sets 16036422004 or a none OE quality replacement 16036422004P for example, and still only pay the same single fixed price shipping cost. Please be aware that this component may have other applications within the Honda model range, so check the part-numbers you order are correct for your model and application. Engine work to carry out?
