I have purchased a Europa kit which was started 19 years ago of wonderful quality workmanship but has an un-started, still inhibited 19 year old Rotax 914 engine. From my research, it would seem the soft-start option is critical to the sprag clutch lasting for any length of time. I have read about the Bullyhawk modules, but they are no longer available and new Rotax ignition modules are expensive. I read on the Rotax forum about a circuit that was home made that retarded the ignition on start-up by a user called Turbo-Tom but I cannot find enough information to work out how to replicate this and Turbo-Tom seems to have moved-on. Do any folks out there know of a reliable home-made solution to the defect that was built-in to the original Rotax engines in the form of inadequate time before the timing switched to fully advanced, which is known to destroy the clutch in short order. My local Rotax importer of course suggests I buy a new engine.

I have been flying behind a 914 that is about 15 years old now. The only change I have made to my 914 regarding starting was to install the newer, high-torque starter. My engine starts quickly and easily. I see no need for any soft-start module, ignition retarding software or any other such stuff. I suggest you finish your kit following the factory instructions and evaluate how the engine start goes before you get into any changes to the 914.
