I have a CEN Racing Nitro RC Truck (Fun Factor ST). I have replaced the engine with a High Proformance engine that a friend no longer needed. I left nitro fuel in it for about 3 months, its 20%. The truck will idle for a short period of time and the low speed and high speed adjustments haven't been touched at all, they have been triple checked to be at factory settings. However it will idle but knock off, could I be using the wrong fuel, I did see a picture of a plane on the bottle, and its a generic brand and its red if that matters. Can anyone help me figure out what happened and how to fix my truck? If I can't fix it, anyone wanna buy it (2 engines total)
Needing Help,
