Yea, i feel like by "primary" you mean "PRI" which is prime, and by passes everything and just dumps gas into the carbs. From now on, only run with the petcock in the "ON" position. This way, you can switch to reserve when you run out of fuel as designed and have enough to get to the next gas station. Hope you got home safe. Once again, i would suggest opening up a single build thread to consolidate all of your separate posts into a single thread.
