Hi can anyone tell me what chain I need for my colwood motor hoe , I have 2 of the chains but missing the one that goes from the gearbox cog to bottom cog . Is there a alternative chain I can use that will do maybe a bicycle chain but need to know length and what sort of links , how many links etc. Hopefully something I can find on ebay cheap unless anyone on here has one . Any info would be appreciated as I’m hoping to put it back together soon thanks
