I put the chain on my 110 today the chain as far as I can tell fits on the front sprocket but I cannot get it to fit the rear sprocket. The rear sprocket is a 49 tooth, not sure what the front one is but I believe I got it from bobbyjim here on the forums and he said it will fit the 110. The chain is a 428H. what am I missing here? any help would be greatly appreciated.
