I'm tellin ya'll guys. Just turn the engine around,move it forward, make a
long prop extension , an idler bearing, raise the gear legs, flatten out the
cage, the prop out front. No more problems with high thrust lines, no more
worrying about losing your nuts and having them fall through the prop....

The main difference with the 582 in terms of jetting is due to the rotary
intake valve instead of the piston-skirt induction of the aircooled motors -
this causes one of the cylinders to run slightly leaner than the other one.
On the 618, which also used the rotary valve, the difference was enough that
the carbs actually had to be jetted differently.
On the 582, though, the difference isn't enough to require different jets in
each carb, but the technique is to jet both a bit rich overall so the lean
cylinder runs rich enough. So, unlike on the aircooled motors, you've got a
bit narrower of a range of mixture to play with before you're too lean on
the one cylinder or too rich on the other. This makes it a bit harder to get
the jetting just right. But the rotax recommended jetting for your altitude
and temp gets you pretty close....

Morning LS/Gang:
Could you explain "piston-skirt indiction" please.

Hi Everyone,
Every once in a while I run across some neat pictures of peoples airplanes,
flying, etc. Do many of you have personal web pages about your Kolbs ?
If so please let me know where I can find them.

Michael, you can view my FSII at http://www.springeraviation.net/. I have
been planning to redo the site as the publish feature has failed and for
that I would like to apologize to all on the list for the out of service
Database. I still have the info but have yet to be able to mess with it.

Hey all,
This is where the skirt of the piston acts as the intake valve. On the
aircooled rotaxen, the intake ports are lower in the sleeve (and on the
other side) than the exhaust ports. As the piston goes up, the skirt clears
the port, causing an opening into the crankcase - the vacuum from the
upgoing piston pulls the air/fuel mixture in in the familiar way. On the
power stroke, the skirt blocks the port off closing it, allowing crankcase
pressure to build up for the exhaust stroke....
The 582 uses a mechanically driven rotary valve to control the intake, which
involves some extra machinery and complexity.
The advantage of the rotary valve, though, is very smooth running and broad
powerband. Sure enough, the 582 runs like a swiss watch... The piston skirt
induction motors are much simpler, but they tend to be peakier and behave
more "2-strokey"....
I still far prefer the simplicity of piston skirt induction.......
There are other induction methods for 2-strokes besides these, such as reed
valves and crankshaft induction (these are common on R/C 2-stroke motors)...
