Listing this because its a known quantity as far as wood gas conversions go.
There is an Indian Article about woodgas dual fueling and spark ignition conversion test done on a KOEL RB-33.
This RB-33 is a triple cylinder clone of the P range.
Arrow engine in Texas was also using a P range clone converted to spark ignition as a well gas fuel engine ( for pump jacks )
I am not the seller and I think the price is way out there ( I would give him $50 for it ) but I am posting a link to it anyways just because I think there might be someone who is interested in this sort of rare engine for Ontario…
