This kit bolts on in place of your recoil and uses a hand crank to preload a internal spring. When the release is tripped the spring drives a starter mechanism and it spins the engine to start it.

Made of steel with steel teeth and some internal plastics

Note: NOT RECOMENDED FOR NON COMPRESSION RELEASE ENGINES AND MAKE SURE YOU REMOVE THE CRANK PRIOR TO RELEASING THE LATCH.

DO NOT over crank or spring failure may happen

This part is decently constructed but it is a novelty for our world and even though its neat do not think its a replacement for a starter box.
