I'm pretty sure the choke is disabled on my 73 c20 350 th400, but this morning is the first time that I can't get it to fire up at all. Turns over just fine. I am officially late. It's kinda chilly (around 50 deg.) but not too bad. Should I walk to the store and see if they have a can of starter fluid? What can I do to get her fired up? Any relevant suggestions would be greatly appreciated.
