Just for fun.  This is an example of one of the stationary engines I collected. It was made in 1902 by the Foos Gas Engine Company.  It was a single cylinder and made 22 HP.   It had a very unique rotary wipe spark ignition, drip oilers and 61″ flywheels.  I was lucky enough to once own it but ended up selling the entire collection to start a business. It ran like a watch. It weighed around 8000 lbs and was originally used in a Colorado mining operation back in its day.  The following is a link to a short read about the company.

This stuff runs through my veins.
