Not yet, a full tuneup is the next project.
Pulled the air horn, then removed the small cap that holds the discharge jets for the accelerator pump, pulled out the weight and check ball. Then blasted the carb body out with carb clean then compressed air. Shot a wad of crap out of the accelerator pump passage whilst doing so. Reassembled and installed. Problem solved...nice strong jet of fuel, no stumble or bucking during acceleration.
Thanks for the help.
