After looking at the video, i was wondering the following.
Do you run that big engine on petrol and you are adding the fog?
Hi Steve
That is correct, gm 305 tbi running on gasoline with the fogger piped into the air filter cover above the TBI unit. Last night was the 1st time I saw any real DC coming from the extraction circuit. Not very much at all really, but it's a start. Hope to repair inverter today and test some on road action.
