The solid deck one has had a later motor put on it at some stage and haven't quite got it running yet. But the reel has quite a crisp sharp edge on it so it sure that it won't need a sharpen at this stage, maybe just a back lap ? Also I'm not really good in telling how much wear is on the chains but I'm guessing the main drive chain and sprockets will need to be replaced. I am thinking about leaving the twin rail one for now and just using it with the real out of the single deck one if this is possible ? And then giving the solid deck a bit of a tidy up. Thanks for any advice.
