Lots of modifications, plus one breakdown; starter clutch broke bolts holding it onto flywheel, simple enough to repair but used 12.9 Cap Screws to replace the failed Chinese fixings. So far all good. Injection wiring harness replaced after I accidentally cooked the earth wire by not re-attaching the engine to airframe earth strap, doh! Three litres used in 23 minutes, mostly full throttle climbouts
