Thanks for the leak down suggestion. I was hoping to not go there due to my lack of experience and short on patience; however it's the right next step. I looked at some youtube and getting to top dead center may be a bit tricky for me, plus it seems I would need to get behind the bulkhead to rotate to get top dead center. I thought my center piece may have been connected separately so I'll see if just that part can be removed. But I did check the next cylinder compression and it was 125. I was kind of hoping to use this compression test guide below as a crude reference, but I can't watch the gauge and crank from the drivers seat at the same time. Or maybe I can rig the gauge to watch from the rear window/firewall while I crank.
