I just read another forum with someone who had the same problem as me and their problem was timing as mine might be. Their solution to the problem was reversing the wires, so black to blue and blue to black and then they used starting fluid to help it get started, which I would use WD-40 like someone suggested in this thread. Would this be safe to try?
OK, in my opinion that is now the stupidest advice ever given here.
Black is engine ground from the magneto.
Engine electrical ground is what completes the circuit between your single wire spark plug and ignition system, the Blue wire side.
Reversing the frigg'n color coded 2 wire ignition system is like thinking if you swap the + and - on your car battery it would somehow help anything.
Lachiepower0402, perhaps you may want to know what you are talking about before you suggest your guesses or really REALLY bad advice again?
Just a tip, take it or leave it.
Just Notes:
WD40 is not a lubricant or starter fluid, it is a solvent NASA developed to de-ice space shuttle external fuel tanks.
Chances are your original magneto actual blue wire coil is not as more foten than not the mag coils ground tab that solders to the magnet broke free and can be fixed in a minute with a soldering iron.
The # in the middle of an NGK spark is the heat range, the lower the number the more heat the plug keeps in.
If you run in cold weather you want a low number to keep heat in.
