from the September 1997 issue of the
Hercules Engine News
by Glenn Karch
Information about the existence of more Sparta Economy engines continues to arrive. A 4 HP model A #602 has turned up in Texas. A 2 HP model A #1372 has turned up in Oregon. In all, since last report, there are now 385 Spartas on the list. At the Hoosier Fly-wheelers Show on June 28, there was a 3 HP model B #3698 on display. No where in literature or catalogs is a 3 HP size mentioned. It is always 2, 4, etc.
The measurements of the bore, stroke and flywheel diameter are the same as that of the normal 2 HP size of that era. Are there more Sparta Economy engines with the 3 HP tag Out there? Maybe it was a Monday morning special where the HP stamper was still recovering from his weekend activities.
Hercules and Sparta engines continue to be well represented at shows. At the Hoosier Flywheelers Show there were 13, with one Hercules, four Economys, four Jaegers, one Renfrew oil engine and three Spartas. At Foos Fever at Coolspring, Pennsylvania, there were 39, with eleven Hercules, twelve Economys, nine Jaegers, two Thermoils and five Spartas. As for me, it was Foos Fever. I exhibited my 6 and 7 HP Foos engines.
