Thanks Frank. I'll have to ask around if anyone within the 2 hour drive to a larger city has an engine timing light. So I'm hoping I found the culprit of the poor engine performance. Somehow my #1 ignition wire was not put on tight or came loose. I snapped it back in and have driven short distances so far without a noticable issue.
It is good to hear that this might have an effect on the vac system. 🖐️👍
