Hi stumpi,
I moved your thread from general chat to all new people as I thought it is an ok start to an intro but I think people would love to see a pic or 2 of your Jet.
In answer to your question yes it has been done before with carb setups.
To help you also let us know what engine your Jet has in it currently. They did come with quite a few different engines and I for one can never remember which series is in what hijet.
Welcome btw
