So in answer to a post I made last week, Ken Ruth has answered my question in an email. He said do not move the shutter speed after it had been cocked. ( he has just serviced the camera a Super Ikonta ) I wanted to know why, here is his answer.............
RE: changing speeds cocked.
On your version shutter the pin that follows the speed setting cam can
be bent going from step to another when the shutter is cocked, when the
shutter is tripped the pin is retracted out of harms way. The top speed
engages an additional drive spring. the shutter tension on that spring
is minimal when tripped but great force is required to shift into top
speed after the shutter is cocked which can damage both the spring end
and the speed setting cam.
