how do you jump a 47 willies with a 6 volt system with only a twelve volt charger or car available?

It has not been started for a few years thus roll starting it is not an option.
I guess I am getting ahead of myself......
What precautions should I take before starting it to lower the risk of causing damage from its long sleep in the neighbors barn.

I know that there is not a ton of info on this car so if you have any other tips for me it would be great because I'm an idiot and mangage to make anything go wrong that can go wrong. Maybe it's just genes but I think these may explain a little :beer: :beer: :usa:

Here is what works on my Ford 8N tractor, also 6v. Just be quick! Hook up the jumpers and start, if no start remove jumpers. easier with two people. Also if it has been sitting for a few years you may want to prim the oil pump so there is oil on the bearings before you start to spin them. Just be advised that this is how I jump start my tractor that will always fire up after one or two rotations, you may start to get the starter real hot.

The Starter will be fine jumping it with 12V..Most people that switch to 12V from 6V use the original starter.. Squirt a few drops of oil in the Cylinders then remove the coil wire and spin the engine over a few times to bring the oil pressure up..Then start it up and it should be just fine..
