I think this is whats wrong with mine also. Previous owner changed battery and sol, but it would start right up sometimes and others, it would simply "click, click" and not crank. If I manually move the piston back off the compression stroke, it will get enough momentum to compress and crank again. So my valves arent set quite right I think.
Before any of those things, check the batter connections for a solid and clean connections. Start with the battery. gyood luck
