Thanks for all the advice! I would have replied sooner but was out to the in-laws for the weekend. My 105 was in a CA 2.6 Extra. Sold the plane..kept the motor. The BME is currently without a home, but I do have an NIB 35% WH Extra I'm considering planting it in. I'd wanted to try cannisters but the lack of headers always stopped me. But you've all convinced me I can build my own!
