RE: MOKI RADIAL Care and Maintenence
All, I have owned a 150 and an older 215 and learned much running them on the bench. Recently I replaced an engine in my OMP Yak 55M with a brand new 215 from Gotz Vogelsang. I am using the APS fuel pump and the Kunkle Turbulator just like on the two previous engines. It is a real pleasure to actually fly a Moki for once. What a true thrill. I am using Amsoil Interceptor at 40 to 1. Airflow has been optimized and all cylinders are at the 190 F range after taxiing in and shut down. It seems that the quality of the Moki's has improved. The finish is finer and the exhaust is far cleaner with nearly nonexistent black goo. I recall the 150 and the older 215 producing a great deal of the dreaded black crud and was all over the place. No I was not running overly rich then or anything else different, same oil too, even later at 50 to 1. I am using a Fiala 32x18 prop. Later I will progress to 50 to 1 oil. At 40 to 1 the five spark plugs show good combustion. I am happy with my 215. -Tom
Noah Butler, Are you still flying that wonderful warbird of yours?
