Suntour accushift downtube shifters with Suntour 3000 derailleur, what freewheel?

A friend of mine has a Raleigh Technium and needed a rear wheel. We got one all fixed up for him and he found a nice freewheel. Once we put it on and I started helping him getting it adjusted, it would not shift right. it would either shift well at the top or at the bottom of the range depending on how I adjusted it.

I realized that it was the accushift causing the issue. The freewheel he grabbed out of the bin was what I would consider a ultra spaced suntour. You know, the 6 speed freewheels with the 7 speed spacing (5mm) so that it will fit in place of a standard 5 speed freewheel. Will I need to source a standard 6 speed freewheel?

You need a Suntour (Maeda) indexed free wheel. Although back in the 7 speed era I used a Sachs 7 speed freewheel with few problems. The spacing between 6 and 7 cogs is wider on a Suntour than the rest of the gears. Roger

Indeed you Suntour 6sp Ultra freewheel has 5mm spacing and a Standard or Accushift 6sp of the day has 5.5mm spacing. Sheldon Brown https://sheldonbrown.com/cribsheet-spacing.html Also you need to make sure that the rear shifter and derailleur are both 3000 as 3000 system is different from the rest of the Suntour line. If your freewheel doesn't have to be period specific, the current Shimano 6 speed freewheels are spaced at 5.5mm and they shift really nice! https://www.amazon.com/Shimano-6-Spee...peed+freewheel

Well you have a couple of options try and find a six speed acushift slightly different spacing deferent from top to bottom but about 5.5 as said. For a six speed either the current Shimano/Sunrace or even Falcon will work OK but not for a seven. Or just go with some new shifters with either indexed 7/6 or friction.

Well its not for me, its for my friend and I think he kind of wants to keep the bike as original as possible as far as the drivetrain is concerned.

I will look through our bins at the co-op and see if I can find one that will work better than his current one.
