Re: 1949 L Gravely
You can use rope, you really do not need the eyelet on the end if it's long enough. It will grab the crank pulley by itself.
I will warn you though, you can use a rope but it's not the best. It's too stretchy. I used a rope for years to start mine, but then I came across some conveyor belting from a factory. I cut a piece off the right length, and then ripped it to the right width. Boy what a difference. These engines start the best when you can wrap the pulley, and then pull it with authority when the compression stroke comes around. Each time the compression stroke comes around with a rope, it stretches and you lose some oomph in the pull. The conveyor belting does not stretch, and I can pull it around much better and it starts much quicker with it.
I just found a short piece of copper pipe for the handle, and used a small bolt and nut to wrap the belt around the pipe and use the bolt and nut to pinch the belting around the pipe.
