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.... ;>) Please do not archive! ________________________________ Message 2 _____________________________________ Time: 03:24:53 AM PST US From: "lucien stavenhagen" Subject: RE: Kolb-List: ROTAX 582 JET NEEDLE ADJUSTMENT/RADIATOR TIPS/ELECTRIC VEST TESTI --> Kolb-List message posted by: "lucien stavenhagen" 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....

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)...
