Hello everyone. I've been reading this mailing list for a bit, and I am very impressed with the knowledge and experiences being shared here. It is everyone here who is paving the way for the rotary installations of the future. I for one am very grateful.

I am currently building a Cozy MKIV and I am seriously considering a rotary. Most likely a renesis, but possibly considering a 20B. I have rebuilt a few engines in my day (piston of course). I am far from needing an engine, but I was wondering if some of you can answer a question? I realize there are in-flight challenges that can only be addressed at that time of course, but how much can you debug/learn from ground testing an engine? Can anyone tell me what can be acheived during ground testing and what cannot? Even though I am far away from a powerplant, I'd like to pick up a cheap engine and start "playing" ;-)

I appreciate any input on this subject. Thanks!

That's great news Chris. Glad you figured out the problem.

I made some good progress this weekend. After trying to prime the oil pump and still not getting any oil flow, I broke down and removed the pan. There was the culprit, big as day. I had a kink in the oil pickup line. Because I am installing an inverted oil system, I have to run the line from the pump back out the pan to the inverted oil ball valve. This line needed a bend, and I thought the hose could handle it, but I was wrong. SO I replaced the bend with metal parts, and reassembled everything. Now I’ve got 60 PSI. I also burped the coolant, and that system seems to be working too.

I did find a couple of leaks that will have to be fixed, but that is all minor work.

Thanks all for the helpful words!

Getting closer every day.
