What parts are included and how complete is the kit?

The RoyalAir 15369D kit supplies the common wear items needed to rebuild a Motorcraft/Autolite 2100 two-barrel unit back to serviceable condition.

Replacing aging gaskets and seats helps prevent fuel leakage and performance issues that become more likely when ethanol attacks degraded components.
