I have use many of them with no problems.

That gap sounds too big.

I think mine came with a piece of paper to set the gap.

Same flywheel is used for either. You don't have to to anything with the magnets.

Put a piece of printer paper between the new unit and the flywheel and tighten it down and then remove paper and give it a try. Make sure the wire coming from it is not grounded.

Per the Briggs shop manual the air gap is .010 to .014. It also states that the flywheel but turn at 350 rpm"s minimum to get the magnetron to fire. I worked in small engine for around 10 years and once I did come across a briggs and stratton flywheel that had a weak magnet. Only one time did I ever have that happen. It had very little spark and nothing would change it. I swapped flywheels and changed nothing else and it had the good purple spark.
