Sfene:
I wonder if anyone has tried to convert a Listeroid to hot bulb ignition? Replace the changeover plug to a hot bulb. Maybe advancing the injection timing long before tdc, the hot bulb being large enough to reduce compression to avoid preignition.....

Just a thought, maybe fun to try one day...

Or the modern version of hot bulb:

Alas, they're not selling them anymore.  I made one of these from Mark Cherry's first patent and converted a gas outboard (Honda 4 cycle 2 HP) to alcohol fuel.  It worked very well.   Same concept as hot bulb but uses a platinum element, heated with a very small current for some fuels.  The tube length and element temp affect timing.
