I have a Como C90 9 (same as ST S90?) That i would like to convert to gas or glow/gas. Are the conversions you have talked about this engine, or the G90 (91)?

I imagine all the details are in this thread or referenced here, but basiczlly what mods to the engine are needed except the 1/4-32 park plug, electronic CDI, and the magnet to trigger the sensor? Is the Como/ST conrod good to go with 20:1 gas/oil?

Thanks in advance.
