Decided to go back to Basics and so got rid of the filter. Noted that although there was a little bit of black soot it was not plugged, but I had mad a tricky sliding pipe that had slid nearly closed.
So started it up using a 120v blower, got the motor running on gasoline and using the fuel shutoff solenoid weaned it onto wood gas.
YEA!!! It works and can mow almost as well as on gasoline.
What a moment, I have worked way harder on this thing than the initial startup of my truck. SWEM
now I still have some heat damaged Flex tube and need to redo the filter so it FLOWS.
