I've got 67 273 commando engine here. It will need rebuild. Dedicated 1/2" pull bar and a socket stays on it so I can stop there and turn it from time to time. WD40 from a gallon can in a pump spray bottle stays there too. A few squirts in each spark plug hole from time to time. I might turn twice in 2 weeks or might be 3 months since turned. Varies with how much time I spend near it ( I might turn it today ).
