Diamond Dust in air and GRRT runs great after rebuild.
It don't come with one, just a Venturi. The carb has to be purchased separately.
Well one thing I did fix my Dust and just need to recover it now. But I found I had a bad servo that works but with the slightest load it wont move. I can barley touch it and it will stay flat. Well now I know what caused it for sure.
