How to drive a Saab two stroke, 2 stroke cross country
Tom Donney drives a two stroke Saab and explains how to use the "free wheeling" approach to help avoid melting pistons on a two stroke Saab.
These engines were designed to run on 95 octane fuel or more. Today's lean ethonal or low octane regular fuels can be hard on your engine. If you travel from state to state your fuel choices vary greatly which can affect your jetting choices. (Just as altitude changes your jetting too). I have driven my 1961 Saab (and other pre-1960 Saabs) from Iowa to all points in USA. Even into Mexico (with my family of 5) and Canada. My way is just "a way", not the only way.
NOTE: Non Saab people watch this and make comments like "too lean", "timing off" or "my two stroke runs all day at full throttle"
All I can say is good for you and your car/motorcycle/airplane/what the hell ever. Come follow me across country in your vehicle anytime you want! :)
Check out this youtube video named "black 93 2-stroke saab on Dyno" you can see this very Saab, which a few who seem to miss the point of this video and seem to think is "too lean" (850GT, 1st design triple carbs, oil Injected engine bored to 74mm) running on a Dyno and foggging for bugs. Just FYI, I also own a Mustang Chassis Dyno (have ran over 100 two stroke Dyno tests), and have a box of Saab jets that I bet cost more that the people who keep typing "it's too lean" paid for their 1st two cars! Plus I have had it and others fitted with AFR gauges...so "NO...IT IS NOT TOO LEAN" :) BTW Come to Dodge and we can take it, or other cool old Saabs for a spin. Safe Saab'in, tom donney
Melkus RS 1000 / 2 Stroke SuperCar Sound
Melkus RS 1000 - This was the supercar of the GDR, the Ferrari of the East.
In the Melkus RS1000 an uprated Wartburg engine was installed. This has the
typical 2-stroke sound.

Yes, You Can Build a Sick Vintage Rally Car - AFTER/DRIVE
Ever wanted to go back in time, when screaming two-stroke Saabs were the
kings of rally? Find out how you can, with Bruce Turk, Saab jedi-master and
vintage rally dude.
On the car's specs Bruce adds: "It now has a 850cc three cylinder two
stroke motor that started life as a 750cc but the block was bored out to
850cc. It has Monte Carlo 850 pistons, a GT 750 crank shaft, a dual Solex
"Super kit Carb, lightened flywheel, heavy duty clutch (extra springs
added) fully ported intake and Exhaust
ports to rally spec II specifications and a Spec II rally 4 speed Saab gear
box which is very rare I might add... Oh, estimated HP is 60 BHP"

Saab 2-stroke barn find
This car had been stored in a barn for nearly 30 years when I found it, and
with good help from my son and a friend organized a rescue operation in the
August 2012. Here is what happened that sunny day south-east in Norway.
Working view of 2 Stroke Opposed piston Engine
Saw this at the Mount Gambier show and had to share.
Really appreciate the interest shown so far.
Some good views of rockers and scavenge blower and a look in the inlet
showing the piston working as the valve plus the injector shooting into a
As a kid I remember the sharp bark these engines made at full noise.
Apologies to anoraks who want to know all the details but it was hard to
hear the chap at the engine because of surrounding noise.
The chugging noise you can hear is the vintage Ronaldson Tippett engine
which is turning this engine over slowly so you can see how it works.
Further notes: It is a 2 stroke cycle which fires every revolution and uses
the piston on the inlet side to open and close the port and the piston on
the Exhaust side to uncover the Exhaust at the appropriate time while the
blower is not to supercharge but to "scavenge" the spent gases ( basically
the air blows in the inlet and out the Exhaust at a slight pressure)

Saab Sonett two stroker testrun
Testrun of a Saab Sonett -67 that's been standing in a barn since 1978.
My dad bought it back in 1968 and used it until 1978. It was standing in a
barn but 2003 he finally decided to start it up again. The oiltank was a
bit rusty and had to be replaced but otherwise everything was ok.
Since then the waterpump have been rebuilt and new soccerball wheels have
Nowerdays dad uses it during the summer. It's a charming car with a lovely
