I have a shiny new ground strap for the engine/firewall and I don't remember where it went. I know it doesn't really matter as long as it grounds, but can someone tell me where they were originally connected.

 

You can see the location in the picture. It is right behind the choke pull off.

 

you'll find a welded nut (or stud)just above and centered on the metal firewall from that bolt in the carb pictured in post#2.
