Suntour Freewheel Cogs


Retro Newbie
I have decided to use Suntour Freewheels. I have a Suntour Winner Pro freewheel. 7 speed. Trying to change the cogs to larger ones - I can only get 2 large cogs (splined) and 4 screw on cogs onto the freewheel, I can't get the 7th one on, unless there is no space between the outer cogs. I checked the thickness of the cogs that I have swapped, they are no wider. The only thing I can think of is thinner spacers or find cogs without spacers attached, as unfortunately some of the cogs have spacers attached. Any ideas?

Sheldon Brown website has some Suntour freewheel stuff. They were a bit off the wall at times and expect lots of head scratching lol

Is it like maillard, where the 7th cog screws onto the inside of the sixth, so it kinda hangs off the side of the freewheel?
