I know that walbro carbs are common on weed whackers and such, and I saw in another thread that someone used one on a HT engine. I have a few of them laying around, I haven't messed with them much because I have not had to, but has anybody put these on an HT for increased performance, or has anyone done the reverse put a china Carb on a weed whacker? I have an old weed wacker with carb issues and the simplicity of the generic Chinese Carb would give the engine a new life and maybe my kids bike a motor.
