Nathan, Thanks for the consistent replies. I find it hard to believe that setting the CO to spec and running the O2 could possibly damage a stock engine. Going leave the O2 disconnected for now and play with the CO between 2-4% to see where it runs best. I'd really like to be able to run stock specs on trips though, for the mileage....Been looking at the LM-1's may follow that route to really be able to see what it is actually doing. Thanks again for all the help...
