Good Morning to all,
Thanks folks for all the nice comments.
Bill, I didn’t change the restriction before running the tractor . If I had planed on running the tractor several hours I would have changed the restriction . The tractor is too small to bring the gasifier up to good operating temp. It wood be like the truck idling for a long period .
I knew the gasifier was left in a good state from previous drives and good deep char bed . With a good char bed it is OK to run for a while at low draw because you are using the char which will be clean .
