Looking at the chassis this afternoon and noticed a few differences, The 3/4 rod that holds the pedals is 3 inches short, the idler pulley bracket is at the wrong angle, the small flat plate that rubs on the belt is wrong, the tags that hold the belt cover on are in the wrong place and holes in the wrong place
I think I’ve sorted now, I’m not putting the bendy bit on the pedal bar as i think its for the drive belt to the deck and I’ve only got one deck.If you look at the photos you can see what I’ve done.
