I've been reorganizing my Cox engine and parts collection an found a real head scratcher. None of the literature and data bases I've found square up with this one:

Single intake port with no booster flutes, slitted exhaust, top fin milled for wrench, not sure about SPI and, drum roll . . . stamped #3 dead center on exterior cylinder wall between exhaust port bottom edge and base.

Clues??

#3 was used on the Mercedes car. Early versions didn't have SPI.

As far as I know, NO Cox Bee powered cars (except for Prop Rods possibly) used SPI cylinders. The wheel drive cars produced so much smoky grease while running under the body shell, that engines with SPI cylinders would crap out on their own exhaust fumes. Since my little queerity of a cylinder has slit exhaust ports, it couldn't have been OEM on a Mercedes either. The data base and literature that I found are all over the place with Venoms and this that and the other high performance plane engines. But there's no way this cylinder can be high performance with only one plain intake port.

Is it possible it was stamped incorrectly? I could see that happen.

Most plausible explanation so far. The #3 stamping looks like Cox/Estes factory work as opposed to some hobbyist running a prank.

Or maybe it was supposed to be a #3 and somebody in the factory just let the thing slide with incomplete port milling work? At what stage of production were Cox cylinders stamped with numbers?
