How to open up rocker arm oil passages.

Well done! Most people start one and never finish. We had a Variez that was donated to the Aviation School (South Arkansas University) where I taught for 12 years. It had 4 different owners before we got it. I retired in 2014 and it still looks about the same. My tail wheel endorsement is "grandfathered" as I flew tail wheel before the endorsement requirement, Same as my complex. However, having not flown a conventional gear plane in a while, some stick time with our instructor would be recommended. As for complex...I do my BFR in the 172RG we have. My neighbor builds ad sells a biplane ultralite. Our ex-mayor has a RV-4.

Nice! I love the Cessna RGs. I ended up owning the '41 T Craft for a few years. Most fun I had flying is a toss up between flying fire watch over logging camps between Olympia WA, the Columbia River, and the Pacific Ocean at 300' AGL and ferrying Cessnas for a local Dealer. Great times!
