You have certainly had your trials and tribulations - but good to see you hanging in there. I once let my old rotary engine sit for six weeks with the intake manifold off after I had the engine severely flooded (gasoline pouring out the exhaust). The flood of gasoline (due to the old auto fuel injection system I was then using) apparently removed all traces of oil from the apex seals and their slots. After six weeks I tried to start the engine and found I had zero compression - the starter motor turned over the engine and prop like it was going to get us airborne. To make a long story short after a week of poking through the exhaust port I managed to break loose all BUT ONE of the seals. Eventually had to take the engine off and even then broke the one apex seal to get it out. Since then I go out and do a start up every two - three week {:>). I suspect that the lack of an intake manifold during that period, the absence of any oil and the high humidity of that period all placed a part. Just one of those things you learn about.

A few days ago I applied some micro on my hopefully now repaired strakes. I still have to smooth and pretty up the micro, but to get away from the fiberglass work for a bit I decided to add fuel to my new strake tanks and calibrate my newly installed Atkinson fuel gages. I had about 25 gallons that I added one gallon at a time, 1/2 gallon to each side. The Velocity has a center sump tank that the two strake tanks dump into. So I added fuel to each side in approximately equal amounts to allow everything to equalize better. I filled the sump tank first and it took just under five gallons. Nothing seemed to leak confirming my air pressure test with balloons a while back. Ok, here is the good part. On a wild hair I turned power on to the plane to see if the rotary engine would turn over after sitting dormant for the last few months with only an occasional hand rotation of the prop. Not only did it turn over, it started. Wahoo. I shut it down right away as I was not in a position to play.....uh, ummm, work on it. But I was tickled it started almost immediately. After having to redo my strakes, this was a nice little experience for me. I am off work tomorrow and I hope to get out to the hangar to clean it up after a lot of fiberglass work. Maybe I will "play" with the engine a bit too.
