Here's a funny little video of my starting it up when it's 10 degrees outside
I apologize for the sideways video, it was taken on a phone and I am used to turning the autorotation off when viewing videos.
The brake warning light is now serving as the alternator warning light for the GM alternator. It will also work for the service brake system. I assume that means if I lost one of my brake circuits, that the alternator would stop charging, but that really wouldn't matter if I lost brakes anyway, lol.
If it ever gets warm enough, I will pull the carbs and send them out to get refurished, and the idle will be a lot better. I feel it starts up pretty nice, considering how worn the carbs are.
