To remove a stripped jet from a carburetor, you can use a screw extractor or an easy-out tool designed for this purpose. First, apply penetrating oil to the area and let it sit for a few minutes. If the jet is still stuck, carefully drill a small hole in the center of the jet, then insert the extractor and turn it counterclockwise to remove the jet. If these methods fail, you may need to consider a drill and tap solution or replacing the carburetor.

to put a bigger main jet, to put more gas to the engine. take the carburetor off. on the bottom are three screws you need to take off. then the carburetor comes in two. the biggest screw head at the top of the brass things, is the main jet. it comes out of the pilot jet, which comes out of the carb if you unscrew it. take out the main jet and put a bigger main jet in. you'll also want a free flow exhaust and free flow muffler.
