Pulled the plugs. I am running on 3 cylinders. plug was as clean as it was when it was put in. Put a different plug in and there was no difference. I do not have a compression tester but that will be the nest step. I tried to plug the hole with a finger to get an idea of compression and I was unable to keep air from coming out no matter how hard I tried to plug it. That is a good sign but not a complete sign about compression. I am thinking it is probably a bad carb. Maybe a plugged jet. Any thoughts?
