Nicholas - this input is very preliminary but today was the big day following completion of the condition inspection, installation of a new muffler and of the AFR gage. I only had time to idle around the hangar complex and get the engine up to temperature; the report is: at low speeds, just a tad above idle, the AFR was 10.45. I have a little work to do on the cowl before a flight but if all goes well, I hope to have in flight numbers tomorrow after improving the idle AFR. Thanks for getting this approach to tuning on my radar screen. (Sure hope it works for me!!)
