Good Evening Dave,
I have a 120 sc running 30 nitro and 18% oil with a 15X11 prop around 9k rpm on a hyde mount, flew great yesterday and today several flights then while coming out of cuban eight down side and throttle up, the engine would not come up to speed, landed and put new YS glow plug in and checked servo, same thing in the next flight, Had good pressure in the tank. The idle is good still. The fuel is filled 3 time before going in to plane. Any ideas?
And if need be what is the address for ys service?
