wiper motor

[Engineer]

Well boys, I was out on her maiden voyage today, all went remarkably well.

Just need to get the Webber tuned as it runs a little slow and has a tendency to die when coming to rest at a stop sign, anyone good with carbs?

Also the wiper motor wiring is proving a bit troublesome, I have one live wire and 3 that are not, have checked the motor itself is ground OK, but have now tried all possibilities (i think) and the bugger still won't work.

That's the last thing before getting inspected.

Any help is as always welcome.
