Hi Jason, welcome to the forum. Keep in mind we don't have the benefit of hearing, smelling licking or feeling that you have being there on site. So some suggestions are helpful shots in the dark. And this just might be one right here. I'd suggest you run a therapeutic dose of carburetor cleaner through there before I wrenched anything. You might have a bit of carbon blocking or varnish buildup out of sight in the carb. A number of snake oils will do the trick if this is the issue. Sea Foam is the current favorite. Chevron Techron Concentrate Plus Fuel System Cleaner rates high in my book. Berryman B-12 Chemtool® Carburetor Fuel Injector and Fuel System Cleaner is another snake oil that has worked well for me. Most of these can be found at WalMart or your auto parts supply house. The instructions on the containers of these chemicals will suggest a maintenance dosage.....I'd be adding a therapeutic dosage. Let it marinate in a 50 / 50 mix a while. Start, run the rpm's up and down and let sit some more.
Another possibility [and there could be 40 possibilities] is a diaphragm issue on the slide. Might want to pull the top cap off the carb and check the condition of the diaphragm if the snake oil does not straighten things out. Classic symptom of problems with the diaphragm is a stumble coming off the slow jet circuit.
