Finally making some progress towards completing the installation of a 1986 Mazda 13B, in RV-9A kit number 90116. Work pretty much ended in about 2008, but retirement is now giving me time to re-engage and hopefully get if flying in 2024. Was finally able to trial fit a Performance Inc prop and spinner that previously flew on rotary powered RV-6, and am working towards an engine run and systems checkout by the end of January.
