MAENLD, is a military version of an AENL. It is a "Heavy Duty" engine, as designated by the Mfr.. The "M" prefex is "Military, "D" suffex is for heavy duty, and means Stellite valves and hardened valve seats. Such a configuration is OK for burning non leaded gas.AENL engines were rated at 9.2 hp at 3600 RPM, though you"ll get longer life if you don"t run it that fast. An ex Wisconsin Motors employee once told me that 2800 RPM was "Best". Your engine has Timken roller bearings, and an oil pump.If it hasn"t been changed, your engine will have a military radio interference sheilded magneto, shielded metallic covered spark plug wire, and a special "Military" sheilded spark plug. If you have magneto,(no spark) problems, standard points, condenser and coil for a WICO, or, Fairbanks-Morse, magneto will fit,,,whatever brand yours is. A standard civilian magneto, and plug will fit also, Parts are readly available, NAPA head gasket is(Fel-Pro) #7686S, complete gasket set is #FS7686S-1 Valves and piston rings are still available from NAPA auto parts. It should have a Zenith Carb, #0-12235, 12236, 12375, or 12522, and the NAPA carb kit # 2-1565 fits all of those numbers. Get yourself a Wisconsin owners and parts book. Or search around in www.wisconsinmotors.com and you can download a free parts book. Wisconsin motors is still very much in business, and you can get parts from distributors listed in that web site, but they seem to think that they"re gold plated, and are very expensive. If you have the Wisconsin parts numbers you can find lot of parts on the web, One other thing---oil, the Wis. owners book lists lots of oil viscositys for different operating temperating..Jungle to Arctic I have lots of Wisconsin engines, and use 10-30 in everything, with no problems
