help on tune up and carburetor issues

[Boog]

I'm with wrenchbender. It sounds like the ignition is not advancing properly. You replaced the normal electrical ignition parts but if the centrifugal advance is n't moving freely it will have next to no pulling power. The weights and springs under the rotor cap need to be clean and move freely. Twist the rotor by hand. It should move but spring back when released. If it doesn't the distributor shaft is likely gummed up down in the housing. It can be disassembled and cleaned or you may elect to go with a new or reman'd unit. 12 volt power supply and it should be good to go.
Most tuners agree, get the ignition right first then the carb.
