Started by watching the DVD on Jabriu engine installation from Homebuilt again. Hung the mount on the engine, changed the prop flange to the 2 inch extension for the X L 601. With help of the engine hoist borrowed from Bills brother (Doug) the engine was hung for the first time. Everything fit very well. Only had to file the lower hole in the mount slightly where it bolted to the firewall. At the hanger day in Mexico last September Pete Krotje said that might be the case. This is such a pretty engine I almost hate putting it inside the cowl.
