Long stroke engine vs short stroke in same ratio of compression does not have same air temperature due to the fact that gas molecules have more than enough time to collide with each other to heat up in a long-stroke engine than in a short-stroke engine.
The Wichman semidiesel engine has turnable propeller blades to drive forward and backward. Also not transmission gear box.
This fishing cutter is shown in the film was taken in Bergen where I live there.☺️
There are 2 different ways to keep the valve closed:
Float with upper valve:
It depends on how great is the force to resist the pressure of gasoline when the float is strong enough to keep the valve closed without being opened by the pressure. A float with good buoyancy will be able to keep the...
Petrol has low density than water then the aluminium float will be lower than in water. Cork as float works better due low weight. Use thinn steel pin pierced through the cork with the tip as a valve and the lower part of the steel pin to keep centered in the float chamber.
The gland rods for valves and piston in stainless steel. And crankshaft can be made of steel or drill rod steel/silver steel. Some time the original cast crankshaft from Stuart in the unmachined steam engine set.
Important to keep steam engines free from moisture: All steel and cast iron...

I have experienced many times casting is not perfect in the ports of the cylinder. In total, I have machined and finished 4 steam engines of Stuart 10D and Stuart triple expansion steam engine.
You mill in small cuts until you get the entrance ports in straight parallels without taking...
I would never do that inside the garage or workshop due to the lack of protection around the melting furnace and no dissipation of the heat above the melting furnace. The safest thing we can do is to be outside in a safe place without risking fire and problems with insurance that does not cover...
I had been involved in metal casting, both lead and aluminium. I would have been aware that the humidity is the most dangerous thing that can occur, that the metal explodes due to steam generation, whether it is in metal or in a mold that is not completely dry enough. Molten aluminum does not...

The firing order 1-2-4-3 is correct in the Mastiff engine.
To example VW Beetle engine firing order 1-4-3-2 and Subaru boxer engine 1-3-2-4.
All engines has same crankshaft with same piston movement.
Location of cylinder number and firing order:
Mastiff engine 1-2-4-3...
Translate to your language and read here, he had trouble with oil leakage before he added oil ring in his Cirrus engine..

As Steamchick mentioned how the oil scraper ring has these forms of oil scraper to keep oil back to crankcase. See this link.. https://www.anglo-agriparts.com/tractor-tech-articles/piston-ring-types-oil-control-rings
