Re: Miata drivetrain into a 1968 SAAB 96
Wow! Great stuff Chas. I am humbled by your superior knowledge of weird foreign 2 stroke cars. Great pics on
your website.Is that sweet orange Vespa yours? I never knew that about Gogomobiles. When I was in Germany
years ago I visited a Microcar museum,very cool.
Send me your e-mail address and will send my pics of the minicar concours I went to.
Keep the popcorn popping!

Auto Union/DKW models do not have an oil injection mechanism, and the fuel/oil must be premixed. However,
I do have a number of the two stroke Goggomobils, and the ones that were slated for US Export were produced
with a "post nasel" drip setup, where oil is metered from an oil reserve tank into the chamber underneath
the piston, with the oil metering device attached to the throttle linkage to adjust metering to the amount
of throttle applied. The German Goggomobils were all premix, but the US export cars had this system
because they presumed the Americans would not be "involved enough" to premix, and that we would demand the
additional convenience of an injection system.
> The American cars were also shipped with an elaborate electromagnetic combination clutch/shifting
mechanism as the Germans understood that Americans preferred automatic transmissions, and this was a
relatively cheap way to attempt to make the shifting easier for the Americans. This sytem actually had
electromagnetic solonoids on the shift shafts inside of the transmission, which would throw the shafts
in or out depending on the electric shifter switch position, much like the Cords from 1936. Curiously, the
cars were shipped to dealers dry with no transmission fluid, and many seized immediately as the American
dealers did not realize that they were expected to add the transmission fluid before running or delivery.

That oil premix system which you describe is much like the petroil pump that others posted a photo of. There
is a small oil reserve tank under the hood, with a crank on the side of it. There is a black knob that is
calibrated in fractions of gallons, which you dial in to correspond to the amount of fuel that was added to
the tank. Once you have dialed in the fuel amount, you simply crank the handle and the device pumps the
