How did you determine "No fire"? An engine may be making good sparks and still not fire if the fuel system is empty or clogged. Where was the resistor that was burnt? There should not be a resistor unless this is a 12 volt conversion. Did you buy a coil that requires an external resistor? The burned resistor may have been the problem but now it is matched up with the wrong coil. It is easier and much cheaper to troubleshoot a problem before parts start being replaced. New parts just cost money and often add new problems. Finding electrical problems can be very frustrating. The first thing I'd do is put the old coil back on it with the new resistor. That is assuming you bought a resistor that is exactly the same type as the one that was burnt. Make sure the points are opening and closing by using a meter to watch the circuit open and close. Never assume anything is "as new" especially if it is new.
