Mark We ended up with a massive 59 degrees spark advance - equivalent to 315mm or 12.5" on the rim of the 24" diameter Lister flywheel.
The MSD (multi-spark discharge) ignition unit we used produces a long and multiple spark ignition events - and once set up, the Lister ran well at 600rpm and produced 2500W electrical output. We would have run at the maximum of 650rpm - but this particular Lister shakes badly with some sort of a resonance above 620rpm. I estimate 3000W electrical output at the full 650 rpm. I have a lot of notes to write up to capture the latest series of experiments - but will happily share them with this group. The Lister type engine is very common across the whole of the developing world - that if we find an effective means to run it efficiently on producer gas- it could save a lot of people vast amounts of money on diesel fuel. Hopefully a similar conversion could be found for the Changfa type single horizontal diesel - as this would liberate the whole of rural south east asia from a lot of their requirement petroleum diesel fuel. The Changfa is a more modern engine - and whilst a spark plug can be fitted - access to the governor is not so easy.
