If it will run on choke, but not normal, the carb needs to be cleaned. It is using the choke to help suck the fuel into cylinder, but will not do it like it should without the choke. Clean out carb and make sire to clean all jets inside. This will fix your issue I am sure. Let me know if I can be of more assistance.
