Some photos of the offending mower for all to see. Originally would have had two rails but has been modified. Geometrically the mower is true so not a bad job. I don't like the fact that bar stock has been used for the front and back of the single rail with a plate welded on top of it.
Can anyone tell me what's going on with the throttle / governor / choke linkages on this 5hp Briggs? It looks like it is missing some bits it needs and has some that don't belong?
