I may have stumbled across something and i need your help, new geniune coil, snorkel, reed valves, everything nice and seal same issue runs bit longer but nothing bogs down as soon as i touch gas that being said should there be a brass ball in the middle hole of the carburator? From the intake side picture uploaded in file? If so what is its purpose, can i plug it in?
