Model builders with KE21 or KE25 engines can retrofit a recoil starter using the Kyosho 74019-15 conversion. It lets you mount the 74031-11 recoil starter for a cleaner, easier starting routine.
The conversion is produced to align with KE21 and KE25 engine geometry, keeping clearances correct and ensuring the recoil starter engages properly. This makes it a practical option for both hobby builds and track day machines.
Installation is manageable for people comfortable with basic mechanical tasks. Prepare tools, read the instructions carefully, and test the starter function before reassembling the model for running.
