I have an old Wisconsin model BKN engine (7hp), which I'd like to try to
start. It has the old pulley with the notch to wrap a rope and pull
start it. (not a built in recoil like on must lawn mowers).

The engine did not come with the the pull cord. I just googled the web,
and found several .PDF repair manuals to download, but none of them say
how to make such a cord. I imagine I could buy a premade cord from ebay
or some where else, or get one from a Wisconsin Engine dealer, but I
know I can easily make one. It's just a length of nylon rope, (like used
on any lawn mower), and a handle. The end that goes on the pulley has a
knot. I already have a handle from a junked mower.

The question is how long the rope should be, and is there a special way
to make the knot on the end, so it releases as soon as the engine
starts.

Do anyone of you have such an engine with the rope, who can post the
length and describe (or post a picture) of the knot? I can buy that rope
by bulk, for under a dollar at the local farm supply store.

Don't need anything fancy...maybe any old clothes line.

Tie a figure 8 knot in the end that will go into the slot in the pulley
and pull it into a ball.

As to length, put your strongest fist against the wall and measure how
long the pull is back to your ear. Make the cord six inches or so
shorter than that.

Use anything for a handle.
