Simple question embarrassed to ask. I have an 11 HP small engine with pull and electric start. I’m setting it up for a home built portable sawmill. The pull start works fine, but due to an injury, I’d like to start it now by battery. I thought this would be simple, but I don’t know how to properly connect it. I’ve manage to start it by attaching jumpers to the battery, with positive lead to the positive on the solenoid, and negative to the fuel tanks bracket. Turn the key it fires instantly. I don’t know if this ties the charging circuit to the battery this way or what is the right way to set this up. I’ve pulled the plate from the key housing and don’t really observe any free wires for this hookup. I need help! Can send pics. Hopefully this is an active forum.
