Holley actually makes a kit for their carburetors that converts to a proper manual choke system. Most of the "universal" ones I used to see had one major issue, the lever was so short that off to on was maybe 3/4" of cable travel where a proper manual choke has close to 2" of travel and the fast idle cam is a smooth piece that allows you to pull it on without having to depress the gas.
