What do you guys do?

Buy pre-made leads? Where?


Make up your own?

If so, what materials do you use/prefer ?

Boots, ends, wire?


I find that a lot of the aftermarket stuff is just

so cheap looking, and am looking for a supply

of quality parts. It such an important part, but

so often I see how people have cobbled something

together, in an effort to get a spark, and then leave

it that way.


Primarily, I asking about a lead, for say a "K" series Kohler.

I use automotive solid copper wire from a roll I bought years ago. Most auto stores have them. I sometimes use old style auto wires(1950s) and modify them. Good Luck, Rick

For my earlier motors I make my own with bulk wire and fittings/ends I get from a couple suppliers that are at several of the shows I go to.

I try and scrounge spark plug boots whenever I can find ones that are not molded on.

I make my own leads.  I use good spark plug wire and crimp on spark plug terminals to get 'er done. 


I always use boots.  Don't shortcut there or else you'll corrode the coil lead.  Rajah terminals are good quality terminals that take the heating and cooling and high electricity well. 


Kohler leads can tolerate resister plug wire, most other type of magnetos, flywheel style in particular, don't like it.

Using solid or stranded copper wire used to generate television interference complaint once upon a time . But as always the quality of the insulation and whether the ignition on computer controlled ignition will tolerate the lack of built in resistance  in copper is a factor  .

Mig welder leads, arch welder leads are too thick, usually can buy at hardware store by the foot, the ends i usually reuse the originals, the boot, depending on the year and MFG can still be bought new.

I stock piled NOS boots for the 50's and 60's.


Everything else the guys above mentioned.
