Hey guys I recently bought a '77 B6000 and it runs and works fine but the lady I bought it from had no clue how to start it or use it, so what I'm wondering is when starting this tractor what is the sequence of operations? I turn the key on then wait some time for glow plugs? do I pull decompression lever on top of the valve cover? and then after this turn this black starting switch ? I don't know some clarification would be appreciated.
