Not sure how many people do it, but most of the old timers/professionals around here, would trust a simple magneto ignition over a electronic module. Good luck either way you go. Top secret files at top of forum will walk you thru a magneto rebuild.
I installed a ton of the Serria 18-5101 modules on my duck hunting customers and they work great!!! Idle's better ,sloppy armature plate no problem and starts easier. I think you can still get them..
