For a whole $11.99 at Amazon.com, you can buy a brand new JRL BoFeng carburetor that has a more heavily built clamping mechanism on it than most of the other NT stock carbs that most of these motor kits come with...Dont mess around with tapes or glues, you will just mess things up with that garbage...lol.
It's the same carb that comes stock with the Phantom 85s...It is what I use.
Here's the link to order it.
