Holy shit. I don't know much about engines and mechanical engineering, but I've been thinking about a different way to build a generator lately, for an electric car, with cylinders that operate together on a horizontal axis, without a traditional crank shaft. And now I stumble over this thing, an actual engine that operates in a somewhat similar way. Apparently I'm not a complete idiot.

🚀💥 "Scientists" propose a trip to #Sedna with #nuclear #engines and solar sails, evidently ignoring that we can't even keep a #Mars #rover going without a flat tire. Meanwhile, actual humans are still waiting for their nuclear-powered hoverboards and flying cars. 🌌🙄

arXiv.orgFeasibility study of a mission to Sedna -- Nuclear propulsion and advanced solar sailing conceptsExploring the outer reaches of the Solar System presents significant propulsion and mission design challenges. This study assesses the feasibility of a mission to Sedna using two advanced propulsion concepts: the Direct Fusion Drive (DFD) rocket engine, based on D-$^{3}$He thermonuclear fusion, and a solar sail utilizing thermal desorption of its coating for propulsion. Both are evaluated for a one-way Earth-to-Sedna mission; however, due to the different performances the DFD would enable orbit insertion, whereas for the solar sail a flyby is envisioned. The analysis evaluates key mission parameters, including delivered payload capacity, travel time, and potential science return. For the DFD, we assume a 1.6 MW system with constant thrust and specific impulse, while for the solar sail, we consider acceleration via thermal desorption and a gravity-assist maneuver around Jupiter. The mission analysis incorporates four key phases: departure, interplanetary acceleration, interplanetary coasting, and rendezvous. Sedna is expected to pass through the perihelion of its orbit in 2075--2076 and then move again away from the Sun. Considering the distances involved, a mission targeting the object would need to be launched "relatively" soon, especially if using conventional propulsion systems, which could require up to 30 years of deep-space travel. In our study, results indicate that the DFD could reach Sedna in approximately 10 years, with 1.5 years of thrusting, while the solar sail, assisted by Jupiter's gravity, could complete the journey in 7 years. The feasibility of science payload accommodation, power availability, and communication constraints is also considered. These findings provide a comparative foundation for future deep-space mission planning.

This is an 1987 sickle bar mower. It features a 3HP Kawasaki FA130D engine. I welded the handle ~10 years ago for the previous owner. They have no need for it anymore (but now I do) and it was stored for 5 years.

I filled the tires, swapped the oil (it was black but not too bad) and the spark plug and put in the correct air filter (previously featuring a way to small kitchen sponge...).

It turns over and "worked perfectly last time it was used".

Right now there is no spark and compression (from what I can tell from the pull cord) is not tooo strong. Looking into the spark plug hole its quite dirty in there.

So I need to take apart the generator/spark gap etc. and check what is going on there and measure compression to know if I need to clean/reseat the valves.

I am not sure how to check if the injection thingy works correctly. I guess I need to separate it from the engine to find the part that drives it. Hopefully it delivers gas...

Any suggestions? Anyone familiar with those ?
