it might! because the explosion power (energy and pressure point of view) from normal fuel is higher than the nitro fuel that chicken engine used.
If the engine is one of those "Rusty" type, the cylinder head will explode into pieces. (or the engine block, if worse )
If you do want to try alternative fuel, You should give alcohol a try. (just make sure you don't use any Johnny Walker thats you have. i'll rather finish the bottle myself )
