Roto Back Plate!

[guinnessdublin]

Hi, was told I could use my Roto start back plate from my FTX PICCO .26 engine on my new Hong Nor Force .28 engine but have found not to be the case.
My Hong Nor engine has the one way bearing on outside of back plate where as my Picco has it internal of back plate.
would the Fastrax Back plate work?
Many Thanks!

Had another look at my existing back plate after buying another one which fitted great but over looked that the dog bone/wand drive cog connection was in wrong place being half way down & not like my old one which was top left corner for easier excess. Anyway turns out I had to pack my existing back plate out with plastic hex nut behind one way bearing shaft which was inside engine for it to work. So all I had to do was remove this plastic hex nut & it fitted perfectly! ??
