I have long wondered about the possibility of using alternate ignition setups on small engines. I see the cheap cdi kits for GY6 and similar scooters and wonder, could they be made to work? Or could a system like the older ford duraspark, GM HEI, or a mopar box work?
Correct me if I'm wrong, but aren't the stock electronic ignitions on these engines simple magnetic triggered coils? Stock ford duraspark distributors use a simple pickup module that could be easily mounted in place of a stock coil, and it could signal the module to fire the coil or coils as the magnets on the flywheel pass.
You could technically run an MSD style box that would give you multispark, and even run a rev limiter so it'd keep you below 3600rpm.
Am I on to something? I want to hear what y'all think.
