Does it use spark plugs?

[EnponAlbeno]

@MrGotsquashed Yes, 2 spark plugs per combustion chamber, 8 total.

I guess this would qualify as a stationary engine lol. I thought this was a 1 cyl. at first- it's so BIG- you can't tell what's what! 86,856ci and only producing 600hp is really weak, but the 39,000 Ft-lbs makes up for it! So, as I understand it, it runs on steam and its function is to pumps natural gas?

[EnponAlbeno]

@MrGotsquashed It's an internal combustion engine. Originally ran on natural gas from the pipeline it was pumping. Now runs on propane - LOTS of propane. lol.

This engine is so impressive! I like to watch this engine.

Oh i read the engine runs with propane now. Better as powered with an electric engine.

Fantastic Rube Goldberg machine. Great to see it preserved and running.

@EnponAlbeno I have some large spark plugs- who knows- maybe they went on this engine!
