Actually - it was marginal at best. The owner (from Kentucky) of one the very few surviving cars of this production run was recently on his way to "a place way up north" - his dream was to drive it north of the Arctic Circle, so he was trailering it behind his moho to get up the Dempster Highway. A breakdown with the Moho left him participating (with this car!) in a weekend evening cruise in Prince George, BC.

Due to the massively unreliable nature of the original powerplant, he had installed a small Honda engine for this particular venture (does that make it a real old timey hotrod?), and my info comes from that source.

If no-one gets the answer by Tuesday eve, I'll post the answer

boothboy Ok. Last guess. either a 1901 Duryea Phaeton Three Wheeler, 1901 Duryea Phaeton Four Wheeler, or a 1901 Duryea Trap Four Wheeler.All three of these autos used Duryea's three cylinder engine. This engine throttled by sliding a throttle plate back and forth across the intake valves. The plate restricted the amount of travel the intake could open. This engine might be Duryea's Peoria type engine.

BuzzLOL . Sounds like an old Oil-Pull engine...

Dave57210 So far as I can find out, it had a 2-speed transmission, but it COULD vary engine speed - just not with a throttle

CrashFarmer2 If it had no throttle I'm guessing the engine would run at a set rpm and in that case it would need some form of variable speed transmission. There are machines that kind of work this way. A lot of agricultural sprayers for instance have a hydrostatic transmission. The engine is run against the governor and the transmission is used to vary that ground speed. Most of the combines I have driven to harvest grain utilize a hydrostatic transmission much in the same manner but I have driven a couple, long ago, that used a variable speed belt to vary the ground speed. These use an adjustable pulley to drive and a spring loaded pulley that is driven to vary the speed.

Pretty early for a hydrostat so I'm going to guess it had a variable speed belt or some other device that I'm unfamiliar with.

Dave57210 Yes, it was an automotive engine - in a production car (If cars could be actually called "production" cars in those days!)

Joe G No throttle? Was this an automotive engine?

Dave57210 No guesses yet? HINT: It was partially a "drip" system, and it had NO throttle

Yup - it was a Duryea

It's fuel system had no throttle ability, but it DID have an extremely weird way to mix gasoline with air to make a burnable mixture. And it was NOT a surface-evap system with air flowing over the liquid fuel reservoir

wretched ratchet While googling some of this I saw one of these that had been sold by an Estate Sale for almost $97,000. Great conversation piece for sure.
