20 hp briggs intec gold (31c707)
Today I went to move it after it has been sitting for about two months and would not start (starter dragging). Having these symptoms several times before, I knew the valves needed adjustment. That did not work, maybe a dead battery? Nope, 12 volts at the battery. Bad battery? Maybe voltage dropped to 2 volts when starting. Replaced the battery today, no change in problem. Through all of this I have checked and rechecked the valves several times. Starter spins freely with spark plug removed. Spark plug does have spark. It ran fine when i parked it 2 months ago, although I can not remember if starter had started dragging or not. I read elsewhere that there is supposed to be a "decompression bump" in the valve train? I am not sure what I am looking for here, is there any video demonstrating this? I fear that I may have a cam that has gone flat...
Thanks for any input
