Just in case my math skills are slipping, how much oil should be added to what amount of 0% nitro fuel? I have a Moki 2.10 (NO pump) that I had in my Wagstaff Extra but I had lots of trouble with it. It is nowhere close to being broke in. It would run forever while the plane was on the ground but the low end idle was rough. When in flight, I could make approx. 2 laps around the field and the engine would die. Seemed very hot also after it died. I was assuming that because the cowl on the Patty was so open that the air was not effectively going over the head thus causing it to overheat. When it did fly without dying in flight, landings were HOT because I could not get it to idle down slow enough for a slow landing. Even on the grass, the plane would taxi with the engine idling as low as could get it without killing it. I have since replaced the engine with a Fuji 50 which is working great but I want to use the Moki either in the Patty or another plane once I can get it running. It sounds like this thread might provide more answers to my dilema.
