Hi there. I want to build my own electronic ignition system with variable timing advance for a homelite 45cc or poulan 46cc engine. I'm currently researching to find all the components needed.
I think an easy way to to vary the timing is with a pic chip. I found some interresting magnets at http://www.leevalley.com/hardware/pa...363,42348&ap=1

I'm looking for timing advance values or curves for these engines. I would also like some schematics for ignition systems similar to CH ignition or ZDZ ignitions. Thanks in advance
