What does the exhaust look like when it is running? Black smoke(flooding)? Blue smoke(oil consumption)? White smoke(antifreeze)? No smoke(A-OK)? Sounds like it is either starving for fuel or it is flooding out. With the fouling plugs, it seems like it might be flooding. Have you checked the air cleaner for blockage? Around here we have a heck of a time with mud daubers building nests and restricting or blocking the air. Easy way would be to disconnect the air cleaner from the carb and see how it runs. Might also see if you are getting a good flow of fuel to the carb. Turn on the gas and open the bowl drain on the carb. You should get a steady pencil wide stream of gas. If not, you have a blockage somewhere up the line. Also, even if you had the carb rebuilt by a good rebuilder, sometimes the passages in the carb will not get cleaned out well, causing problems. You can't just soak out a cast iron carb and expect it to be clean. You have to run the proper size drill bit down each and every one and be extra sure they are clean and free of dirt and rust.
