Its a 12 volt front mount. I don't remember the gap off the top of my head, but i did it according to specks. I have done some reading on others with this problem. I am beginning to wonder if its in the head like you mentioned. What do I do to check the head?

Do you have a propane torch?? If you do when it starts running bad take that torch and wave it around the manifold area. DO NOT light it. It it smooths out when you do that good chance you have a bad manifold gasket. Also check you spark when it starts doing that and make sure you have a good blue/white spark that jumps a 1/4 inch gap or more
