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.
