Topic: Idiot forgot to stagger the rings

[lrutt]

Not all 2 stokes have transfer ports , I think, so reedvalve or rotary valve engine may run without pins.

 here is what I do with rings ;
 Top ring 180 degrees AWAY from point between plug and exh valve, tho other 120 degrees from that..

 The motors ran great, little things CAN make a difference.

Ring spinning Theory;

 If it true..your compression will get higher soon if you put them in straight.

Would I tear it apart ..probably not..

rotary valve and read valve do have transfer ports. I'd love to see a 2 stroke work that didn't have a transfer port, unless it's supercharged.

they all have transfer ports,how does the charge get from the crankcase to above the piston?not including detroits.

One thing to think of, if the rings don't rotate you will get a gap in the wear pattern in the cylinder at the top of the cylinder where only the top ring reaches and the same at the bottom where only the bottom ring reaches.

That is so much common sense that pretty much sums everything up....

And yet it doesn't occur on two strokes.     But then again a stroker is likely to be rebored before this happens.
