not sure I understand "repolarize the flywheel magnet "
It is a permanent magnet? all the B&S flywheels of that era are/were magnets placed in the flywheel - so you aint gonna fix that ! I too think .10 is a weee bit big!!! When I set the coil, I would take a dollar bill and fold it once and slide it in,rotate and put bill back in pocket! I suggest you do that too.

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. This post was edited by McBride at 12:19:54 12/31/12.

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.
