A Brief Word

28/4/24 Ethanol and Engines Ethanol fuel is 200 proof corn whiskey, 120 octane, and a super engine fuel. It can be mixed in any way with gasoline, even 100%. It will start poor in cold weather at higher ratios. It is a strong solvent and is best used at 85% or less. For working tractors, 50% gives more power and cleaner exhaust with only carb adjustments. Modified carbs can use more. For dual fuel tractors, ethanol mixed with kerosene makes it possible to use kero with the hot manifold and the gasoline head. For hit and miss engines in a show atmosphere, ethanol makes for much more pleasant breathing. High concentrations will eat the solder out of gas tanks, so they should be drained. For souped up pullers, ethanol is the perfect fuel.

Gasoline is a horrible fuel, all the way from drilling to spills, to long after it is burned. It is toxic and carcinogenic. Ethanol is a USA made renewable fuel, and is infinitely kinder to the air. Ethanol is available from your gas delivery man.

Soydiesel fuel, made from soybean oil, performs just like diesel fuel except that it has no sulfur and has a pleasant odor. It is perfect for show diesels and indoor applications. You'll like it! Call 913-341-0300 to order any amount. Ron TePoel, Oronoco, MN 55960-2208.

28/4/25 Pioneer Gen-E-Motor Q. I need any available information on a Pioneer Gen-E-Motor, Model A, Type SS 3780, sin 2-13730. Keith C. Stone, 206 Tanglewood Dr., Rochester Hills, MI 48309.

28/4/26 Case 10-20 Q. I need information on a 1918 Case 10-20 tractor, s/n 17215. What was the original color, and where can I get decals? In a 1916 parts book it appears that four different magnetos could be used, and two different air strainers? What is correct for the 1918 model? How many of these three-wheeled tractors still exist? I hope to have this tractor restored for the 1993 National Show hosted by Branch 13 in Grass Valley, California. Jeff E.Wallom,10365 Pringle Ave., Galt, CA 95632.

A. We're not certain if this model was Ditzler 40249 Green or not. The J. I. Case collectors have worked out a lot of the details in this regard, and perhaps even a 10-20 owner might be able to contact you regarding your questions. Accurately defining who did what and when they did it is sometimes very difficult, if not impossible. Having never done the footwork necessary to restore one of these tractors, we would encourage someone who has this experience to contact Mr. Wallom.
