Have you ever had an ignition related misfire at the RPMs you run? If you haven't, I wouldn't think you would need the crank trigger. That's my opinion anyway. Other's may have different opinions.

I pull a 12hp kohler with gm points,never had a bit of trouble with them,just got to make sure you get them set right,feeler gauge or timing light.Unless you are really crankin out way high rpms,a crank trigger isnt a issue.

Crank trigger ignition does provide a more stable & hotter spark, but only at high rpms. Our dyno tests show that it helps very little with a low rpm engine. But if you want the ignition points to possibly last the life of the engine, use a stock 3.0 ohm coil with a 1.8 ohm ballast resistor. Because the increased resistance allows a very low current (flow of voltage) to pass through the points contacts, resulting in much less electrical arcing of the contacts. This will drastically reduce the premature burning away of the platinum on the points contacts. The ignition system will still provide a hot spark because an average small engine requires only a fraction of voltage from the coil.
