I took of the valve cover and checked the valve clearances. They were way off. Set them to .0004 regardless of what the manual says. Problem solved. Make sure you check and set the clearance at top dead center of the compression stroke.
You may have to adjust the valves. I just had the same issue. Replaced starter, solenoid and battery. It was the valves. thay were out of adjustment on the compression stroke. Taryl Dactyl videos `on Youtube will help you out.
