Overview

Sky-Tec factory new starter adapters for Continental engines. The starter motor bolts to the adapter and connects to an input shaft. This shaft has a worm gear attached that turns a larger brass gear.

When the engine starts, the starter is released and the spring opens allowing the shaft to turn freely within the spring.
