  My mom just passed away last Sunday. After over 10 years of my life revolving around her needs I am now completely lost. These videos have always brought me a sense of peace and I'm hoping the same right now. Thank you for your videos over the years Mustie.

  Most general aviation aircraft engines- Lycoming and Continental- use a similar spark plug and ignition wire set up. The spark plug threads are 18mm.

  Mustie is the Bob Ross for therapeutic Sundays. Great demeanor and I love the way he teaches you in simple to understand terms. Great job on this engine. I hope it brings you joy for another application down the road.

  Regarding the direction of rotation: Forward-swept vanes are very common on centrifugal fans/pumps and kick the flow forward to create higher flow speed/volume at a given RPM, with the side effect of increased loading of the motor when inflow is restricted and unloading the motor when outflow is restricted. With backward-swept vanes, the fans/pumps have to spin much faster to create equivalent flow, but are fairly insensitive to flow restrictions and can create higher static pressure. Vanes that are flat and strictly radial have a flow characteristic in between the other extremes.

  Cold War era. It was meant for extreme operating conditions in Siberia, were war to occur. The Germans learned in 1942-43 that the oil in their tanks would freeze locking them solid. They had to light fires under the chassis to thaw it out. That is the reason for the recirculated exhaust gas around the crankcase and oil pan.

  That flywheel blower acts just like any other centrifugal squirrel cage blower, catches the air, then flings it outwards.

  Mustie1, retiring from the Military after 23 year many years ago and had to run small generators while in the field they only had 2 modes. Start with a fast idle and full throttle as they were built to run for days, weeks and longer. No low idle on any of them and the larger generators the same way. BTW air routed down was to help the engines run in extreme cold weather, I did both hot and cold weather training and the same generator was used for both as you take all your equipment with you.

  It&apos;s an 8 cubic inch with 1 1/2 hp, meant to run full tilt all day. &nbsp;It&apos;s like a 3 1/2 hp B&amp;S lawn mower engine. &nbsp; The ones I have were built by Lycoming, the airplane engine maker to pretty much the same specs. &nbsp;That &quot;muffler&quot; might be a spark arrestor. &nbsp;The shrouded plug is to make sure it doesn&apos;t &nbsp;give any electronic noise that could be picked up by a radio, since it could be running a generator powering a radio about 2 feet away. &nbsp;I have 3 one cylinder, 3 two cylinder and 2 four cylinder engines, they all use the same cylinder, head, piston and con rod. &nbsp;The fuel pump is to pull from a G.I. 5 gallon gas can or other can. &nbsp;If the output shaft is tapered it would have driven a generator supporting the that end of the armature with the crankshaft bearing. &nbsp;This one seems to have an oil bath air filter on first two versions, next two versions have paper air filter.

  That engine appears to be set up for COLD weather running. The air heated by the head/exhaust is used to warm the oil. The overhead valves were FAR ahead of B&amp;S engines of that time.

  It looks just like an engine I bought only a few days ago. What are the odds! This video will sure come in handy. Love the channel!

  This engine was made in several versions. The one you are working on is a 1AO8, the others are 2AO16, 4AO32, 2AO42 and 4AO84. The first number of each series is the number of cylinders. These are referred to as a military standard engine, and the ratings are derated because the 4AO32 is rated at only 6 horsepower. The one you had in this video is 1-1/2 hp. Some websites claim the actual horsepower is between 18-20. The 4AO84 is sometimes used in experimental aircraft.<br>The 4 cylinder engines have electric start on 24 volt, but certain BMW car starters can be made to start the engines, since they are 12v.<br>The military standard engines are really nice in that they shared common parts, like pistons, valves and valve covers, etc.
