I have looked at this picture over and over and I think you have the wires on right.After thinking about it,maybe you dont have the motor on the right stroke.Either that or its advanced too much.I think the rotor should be just past the lug on the cap at TDC.It ought to hit if its right on the lug,but maybe it wont.Other than that I dont know,others have said its turning the wrong way,not the right mag,so maybe there is something else.Thinking about that,if it sparks the plug,and when you turn the motor over 2 times and its back to the same place you started at,then it doesnt matter which way it turns as long as you have the wires on in the firing order right according to whichever way it turns.I could be wrong,and the possible problem I could see is that if you turned it the other way from the way it is supposed to turn it might fire at the wrong time so as to not run.I know very little about a mag,but if you can turn it some like a distributer try that.Something tells me you are on the wrong stroke.When you crank a motor over I think there is a time when it can blow compression out the spark plug hole but its not as strong as when its on the compression stroke.I mean if it turns over fast some air could come out the spark plug hole on the exhaust stroke,but it wouldnt be very strong since the exhaust valve would be open.On the compression stroke it will blow your finger out of the hole unless the valves arent set right.Maybe you need to pull the valve cover and see if both vavles are closed on number 1 when you are at Tdc,then pull the cap and see where the rotor is pointing,that will be number 1,then use your crank cause it will have to turn the motor the right way and turn it a little,whichever way the rotor turns,thats tells you where to put number 2 wire then 4 then 3.After you get wires on the cap right,keep turning motor untill you have turned the crank 2 times,if the rotor is where you started at it should run,if its not,then you might need to ask somebody smarter than me about it.Maybe its the wrong mag?
