Yes sir but unfortunately only for about 6 hours on Thursday, we were camping that weekend but was able to slip away for a bit. Were you there?

Were you at the fall show?

I have often thought about something like air Injection for petrol motors. Something like a forced carburettor I spose one would say.
Of course if it had any merit, It would have already been done.

This very unique bit of history dosen't seem to look quite right in what appears just to be some shed somewhere.  I think it should be in a museum somewhere people can come and admire it. Better still if they could find the missing parts and getting running again.

Everything about machinery like that makes me marvel. Not only were things designed to be functional, they were done to look good as well.  Even the castings of the engine itself are done with an effort to please the eye and the details from there even more so.  The makers proudly put cast or stamped brass plates on their engines  and things were often painted with scroll and detail work as against now where you are lucky to get a crappy sticker on a cheap bit of coloured plastic.

Quality on par with yesterdays standards can't even be bought as luxury anymore.  They just don't have the knowledge let alone ability to manufacture to those sort of level now days.

"bad money drives out good" started as Gresham's Law in economics but just fits this unpleasant drift in machine design and production.  Thank Goodness that it is not a "Law" nor is economics a science.  I marvel at yesteryear's standards just as do most of the people at this forum but every once in a while I'll see a "machine" built to fuzzy standards plunk away day after day leaving me flabbergasted as to how does it do it and who was the genius level jerk that designed and built it.

I can honestly say coolsprings is responsible for my obsession with stationary engines, on a side note how loud are these rustons? Im designing the exhaust and it takes a little bit more thinking with the exhaust mounted fuel filter assembly that came on the engine. I was thinking about a side dump but also considering a vertical stak but its kind of busy in that area with that and the air start valve.

Check out my youtube "contaucreek" channel for exhaust music. If slowed down and not loaded its about as loud as a dog panting. Carry on a conversation without yelling.

So, what makes it "pant" instead of "bark" ?   Valve shape/speed, muffler ?

My guess, and see how good it is when the knowledgeable chime in, would be late valve opening of a long stroke engine meaning the cylinder pressure is already well down on the low compression to start with, large valves and exhaust that mean the gas speed is slow and the fact the engine is slow turning and not under a lot of load, the fuel charge is is small for the capacity.

See how far off I am.  :0)
