Thanx for the encouragement. As for the filtering, if the initial oil supply was kept scrupulously clean, I am not considering filtering. At the small amounts of oil being used I would not think it would be necessary to reuse the oil a great number of times. Changing the oil after an hours use I think would be more than adequate to get rid of any contaminants. Even in this case of an old engine, it passed less than an ounce of oil thru the engine after 45 minutes of running WOT so changing the oil would not involve a lot of oil. Hopefully with a better seal by the rings, less oil would be burned and less blowby would contaminate the oil. Besides, filtering would only remove the solids and the only solids should be the wear materials from inside the engine which I hope would be minimal over the period of an oil change.

Next part of this experiment is to find a fuel that would run the engine reliably as glo fuel is not sold without oil and is getting expensive. I am hoping to run the engine on go-cart methanol or a gasoline/methanol mix with no oil. Possibly I may have to include some nitro in the mix to improve the idle or reliably. I am not looking for the last bit of HP. That is not the purpose of this excersize.
