Engine Dieseling - Options?

T slot is a decent "square" shape, mixture screws 1 turn out fronts, 1/2 turn out rears - idle is right at 1150/1175 -

one thing to note that the dieseling didn't stop, just "lightened" a bit, was gonna put a hose in the tank and blow some air in to try and mix the octane boost, figured what the hell, as I noted with the battery low I called it quits, previously when the battery was low it noticeably affected running, figured I needed everything to be good when checking things - I do know just by exhaust its a little rich - I will be dialing back idle screws when I get back at it, also thinking about rejetting my 670 and putting on there
