hi all.i have been given an older lawnmower with the above engine.i've completely stripped and cleaned the carb,but the linkages were in a provided in a bag.i have a feeling some bits may be missing.i downloaded the B&S manual for this engine,but this doesn't show which linkages go where.,only an exploded view.does anyone know of a website that actually shows the linkages,or some other way of figuring where everything goes..Also,there are 2 wires from the magneto,do they both go to ground?thanks for any help.hans.(in NZ)
