I seem to have not spark. What is weird is when the starter is turning over, there is not spark or fire. When I let of the starter, it sparks. I see it on the plug. When the plugs are in when I let go of the starter button, it fires for a sec but does not run. I am guessing the voltage is dropping when the stater is engauged. When I relase the starter button, the voltage jumps and it fires, but wont start.

make sense?

What can I check?
