What engine is this ?
the blade root looks like the "redesigned" MAS props that are no larger than 11" so i'm guessing the engine is no larger than a .60.
the little gusset at the mounting lug looks very ENYA
the way the carb mounts looks very ENYA
i can't see a separate backplate which is very ENYA
maybe i'm wrong but it looks to me like an ENYA with an incorrect carb and an ugly muffler that don't fit.
