When the voltage regulator is connected i don't have power in the carburetor (shock and low speed),
When voltage reguklator is disconected i have power in the carburetor and the car runs for few seconds, I replaced the Voltage regulator, alternator, new ignition switch and doesn't help..

another thing I notioced the gas pump is running all time never shut off either if the gas level is above the "level dot" in the small glass located in the carburetor (with the VR disconected)
I clean all the fuse box and also rebuild the carburator and replaced the filter.
could be the electric points?
the exhaust manifold has a small crack could be the reason?
relay?
coil?
capacitor?
Please help
