1964 Valiant "Get Runnin & Drivin"
I inspected the heat riser valve when we got back from town and it does open some at idle when hot. Also when given any gas at all hot, it opens all the way. So the spring works as designed. Took Kitty to lunch today to her favorite Mexican joint in Gray. Again, about a 22 mile round trip. Vixen rides solid as a rock. Zero squeaks or rattles and she just zips along real good.
