Thanks for any help.

1977 Controls did not have lanyard kill switches. However, I seem to recall an accessory one that actually turned the key off. But don't remember the details on that one.

EDIT: Yep, found it. Part number 173566 fits 1973 through 1978. It was an accessory kit, did not come with the controls. Yanking the lanyard out turned the key off.

I can't tell from your post if the switch won't turn on with the broken key in it, or will the switch turn on but it still won't start?
If the latter is true, the broken key shouldn't be the problem.

The original question is confusing. It was asked if the broken key could keep the motor from starting. Well hey, if you can't turn the key, of course you can't start it. I don't think we are reading the whole story here.
