Hi Chris
I think Cobba pin the point, and if you have a micro budget, dont jeopardize it. An HR (2, 3, 4 or 6) are direct injection and high RPM.
LEF members that uses WMO or WVO has low RPM engines Lister CS or listeroids, and thoes "fuels" need fine filtering, centrifuge to separate water, mixing to start and even heating to flow better.
Do you really need 10 KW? or 5 or 3 is sufficient?
Just a few cent to the rant!
