Two of these scooters were two strokes. Any blow by during the compression stroke would be mixed with the next intake charge. This would totally negate any effect of fuel slipping past the rings. Similarly in a four stroke car engine, the gas fumes in the blow by get sucked up into the intake via the PCV and burned that way. Otherwise if just one percent of the fuel slipped by the rings we would probably have about a gallon of gas diluting our oil when we changed it.

If your trying to imply that acetone some how magically keeps fuel from getting past the rings I suggest you try a different approach. This argument won't get you anywhere.

Timing is a bit more complex than that , more timing only means more efficient if the engine is retarded to begin with. You add timing if the flame front hits the piston late, you take timing if the flame front hits the piston early. When it hits it at the "right" time which is about 15 degrees past TDC then you are at ideal timing.

Maybe, just maybe, his acetone ratio changed so much in the first 6 months for experimental purposes, maybe he just didnt have the ratio correct.

If he says that its important to be very precise in the very beginning and he has been experimenting with this for more than 50 years, why would the latest 6 months of experimentation change his ratios so drastically? Typically people start with big changes and narrow in on an optimum amount by making little changes at the end. You would think after 50 years he would be making very very minor tweaks.

I have seen a couple mpg improvement so far and im not being precise really. Also, is he saying he will give you the treasure map with the purchase of a shovel, no, he gives you the treasure map and if you feel it looks like a probable location for treasure he just happens to also sell shovels. The device he is selling is useful with or without the acetone.

Not quite. He gives away a fake treasure map. People go follow the map and come back to him and say there is no treasure. He tells them that they can't dig it up by hand and they have to use a shovel. He sells them a shovel. people follow map and use shovel to dig. The people still don't find a treasure. The people wanted treasure and end up with a shovel they never wanted to buy. The only person with treasure is the scam artist selling the shovels.
