1970 t/a all stock. Hard to start cold fires right up after it’s warm. I’m pretty sure the choke isn’t working right being the cause. Everything seems to be adjusted to spec and I can make the choke close completely on a cold engine but it won’t automatically do it like it should when you first pump the gas to prime. The choke valve only closes slightly as if there’s not enough force. If I do it under the hood there doesn’t seem to be any real resistance and I’m able to close it completely once I open up the throttle valves. Any ideas? Can this be adjusted? Like I said when it’s warm and no choke involvement it cranks immediately.
