..these are actually coiled or spiralled platinium wire _catalyzers_,
the methanol vapor-and-air cylinder charge fires from the _combined_
effect of compression and the catalyzer.

..these are the "semi-diesel" kinda engines?  Slow turning monsters, 
more like 300-500 rpm.  I'd get some used Japanese auto engines instead,
for throw-away service.

..the most recent use I'm aware of, is WWII fishermen bleeding the 
combustion chamber for idle on those "semi-diesels" on wood gas,
is this "idle-valving" in "Gengas", or do I remember it from my 
own version?
