340 Chugging instead of Reving

I saw that but it’s just an idle video with a quick rev at the end. Drive it and video the tach and stand on it. Show us what it does.

I have it torn down a little right now. Drying the cylinders and cleaning the plugs.
Swapping out the distributor and ignition box then putting back together. I'll shoot another video at that point. Due to finding fuel in the cylinders, I have only been test running in the shop and avoid long run times or driving it to avoid washing the cylinders and causing damage.
