Gordon,
Welcome. The thing with the hose and wire that you mention is a switch to cut the ignition if the engine starts to run away in neutral, yo prevent the engine from grenading.
If it won’t run well at low speed and the carb is clean and adjusted properly, and the ignition is in good shape, it could be that the compression is low. Proper ignition timing of the points opening 180 degrees apart is critical for a good idle, so do what you can to eliminate variables.
