D, re the 100:1 mix. It is for lubricating the valves. Many on this forum run the MMO @ 100:1 full time. It is not enough to do any sort of fouling and it does a good job of carrying the oil to the valve stems (the part that sticks) and the cylinder walls. The TCW-3 is specifically designed to burn with gasoline while lubricating. That's just over an ounce per gallon.
Are you using any additives at all?
