I think that will help, but you may simply have a lemon carb. Still the Perry pump could help. Just be sure that the pressure is adjusted so that the high end has to be opened up, yet more than enough to get a good rich mixture. You can adjust it to lean the mid range as well, but that usually means a lean mixture at high speed. Most carbs will run richer at midrange if you have sufficient muffler pressure. The instructions have more detailed info on how to set it up. Just be sure you get it right.
