It sure looks to me that the FW is a non indexed design. So no wonder that a system that failed in the market with all the right parts might work poorly with the wrong part. SunTour's Acushift system was cable tension focused and the spacing between cogs was not consistent across the cog set. So modern, equally spaced cog sets won't also match up well. Is that a Sedis Sport chain too? If so then also pre index spec. The last bit is the large amount of open chain between the cogs undersides and the guide pulley. Andy
